MicrosoftEdge
GetWindows doesn't respond after downloading
If you do the following, it will not respond. This occurs from version 133 onwards. msedgedriver - Edge version combination 134 - 134: Occurs 133 - 133: Occurs 132 - 133: Does not occur chromedriver - Chrome combinations, both 133 and 134, work normally. (1) Start msedgedriver.exe (2) Open a browser (3) Navigate to the following site (any site will do) https://forest.watch.impress.co.jp/library/software/7zip/ (4) Click the download button manually (5) Wait for the download to complete (6) This occurs once every few times when GetWindows is called http://localhost:xxxxx/session/$sessionid/window/handles (7) If this does not occur, manually return to the previous page and repeat steps (4) to (6).
Note: This is more likely to occur if FindElement or similar is called between steps (4) and (6).
Attached is the log file.

I am scraping internal company web pages. Since I cannot share the internal pages, I used the 7zip download page as an example in my initial post, but this occurs infrequently. It always occurs on the internal pages.
I have attached the log from scraping the internal pages. The file is named EdgeDriver03A.log. The internal pages perform download operations in a popup window from the main page. After the final AcceptAlert, the download starts, and once the file extension is no longer "crdownload," I call SwitchToWindow, but it times out.
Hi @Okamo1029 , how often do you get this issue? I tried to manually test the issue with Edge 134.0.3124.66 but cannot repro the issue. I also created a test app and ran 20+ times, still cannot repro:
`using OpenQA.Selenium; using OpenQA.Selenium.Edge;
namespace WebdriverGetWindowNotResponding { internal class Program { private static void GetWindowInfo(IWebDriver driver) { int tabCount = driver.WindowHandles.Count;
for (int i = 0; i < tabCount; ++i)
{
Console.WriteLine(string.Format("GetWindowInfo:driver.WindowHandles[{0}]:", i) + driver.WindowHandles[i]);
}
Console.WriteLine(string.Format("GetWindowInfo WindowCount={0} CurrentWindowHandle:{1}",
driver.WindowHandles.Count, driver.CurrentWindowHandle));
}
static void Main(string[] args)
{
EdgeOptions opts = new EdgeOptions();
opts.AddArgument($"--app=https://forest.watch.impress.co.jp/library/software/7zip/");
opts.BinaryLocation = "C:\\Program Files (x86)\\Microsoft\\Edge\\Application\\msedge.exe";
var edgeDriverService = EdgeDriverService.CreateDefaultService();
//edgeDriverService.EnableVerboseLogging = true;
var driver = new EdgeDriver(edgeDriverService, opts, TimeSpan.FromMinutes(2));
var url = "/library/software/7zip/download_11607.html";
var download = driver.FindElement(By.XPath("//a[@href=\"/library/software/7zip/download_11607.html\"]"));
download.Click();
GetWindowInfo(driver);
Thread.Sleep(5000);
GetWindowInfo(driver);
driver.Close();
driver.Quit();
}
}
}`
Thank you guangyuexu for your prompt reply. I understand the issue of frequency of occurrence. I will search for pages and procedures that frequently occur on public web pages.
This issue occurs 100% on our company's internal web pages.
As a supplement, the scraping tool is created using the following TinySeleniumVBA and Excel VBA. This is to distribute it to many people without requiring installation: https://github.com/uezo/TinySeleniumVBA/blob/main/README.ja.md
Thank you guangyuexu. I have created a simple page that replicates the screen transitions of our company's internal web page. The file is named docroot.zip. We have confirmed that the issue can be reliably reproduced on this page. (We used the command "python -m http.server 8000" to run the web server.) Please extract the contents to an appropriate folder. If Python 3 is already installed, you can start the server using svexec.bat.
Here are the steps to reproduce the issue:
(1) Display "http://localhost:8000/main01.html" (2) Click the "sub window" button to display the popup window (3) Transition between windows and iframes (4) Click the "download" button to display the confirmation dialog (5) Click the OK button to download (6) Wait for a few seconds (important) (7) Transition between windows (the issue occurs here)
Below is the actual VBA code. I'm not familiar with other languages, so I'll write it in VBA code. Sorry.
Dim strW01 As String 'Variable to store window ID Dim strW02 As String 'Variable to store window ID Dim strMsg As String 'Variable to store alert message Dim oS As WebElement 'WebElement object Dim nWin As Long 'Number of windows
'Open the browser Driver.OpenBrowser
'Navigate to the target page Driver.Navigate "http://localhost:8000/main01.html"
'Get the window ID strW01 = Driver.GetCurrWindowHandle 'Get the current number of windows nWin = Driver.GetWindowCount
'Get the object of the "sub window" button Set oS = Driver.FindElement(By.ID, "mbtn") 'Click the button oS.Click
'Set the newly popped-up window as the target Call Driver.SwitchLatestWindow(nWin)
'Get the window ID strW02 = Driver.GetCurrWindowHandle
'Switch to the inner iframe Call Driver.SwitchToFrame("dl01")
'Switch to the inner iframe Call Driver.SwitchToFrame("dl02")
'Get the object of the "download" button Set oS = Driver.FindElement(By.ID, "dwcb") 'Click the button oS.Click
'Get the message of the confirmation dialog strMsg = Driver.GetAlertText() 'Click the OK button of the dialog Driver.AlertOK
'Wait for the download '[Important] Wait for a few seconds here, it always happens Sleep 5000
'Set the popup window as the target (this command will cause it) Call Driver.SwitchToWindow(strW02)
That's all.
We are not sure of the relevance of this issue, but since version 133 of Edge, WebDriver no longer responds when the “edge://downloads/” page is displayed even once. (This is also the case with version 136.) We believe this may be related to the change in the download UI in the following update. https://learn.microsoft.com/en-us/deployedge/microsoft-edge-relnote-stable-channel#version-1330306551-february-6-2025 *We use translation software and Sorry if it is not clear.
