Clipboard Exception on Startup

[Positron010]

Describe the bug/issue I have Flow starting on machine startup. Each time I restart my PC, I get this .NET error when Flow starts. I then get a dialog to either quit Flow, or continue. If I continue, Flow works normally. Here is the exception text:

Clipboard Operation Failed

************** Exception Text **************

It is caused by the clipboard plugin. Is it reproducible everytime starting flow?

[Positron010]

Hi, Thanks for your reply. It happens whenever Flow starts with OS startup.

It doesn't happen if I start Flow after staring the OS. However, there are situations where Flow won't launch if the OS is already running until I restart.

Thanks

I found the exception has been reported before. https://github.com/Xenolphthalein/Flow.Launcher.Plugin.ClipboardHistory/issues/3 Let me see whether we can get the author of the plugin to fix it.

Hey @Positron010, what do you mean by this? I found when using Flow with Clipboard plugin, that when you close flow and relaunch it, flow seems not to start up, but going into task manager, you actually see flow has a process running and terminating it will then allow flow to launch. Is this the problem you are experiencing also?

[Positron010]

Hi @jjw24, I didn't notice that the task is still running, but I just checked now, and yes, that is indeed what is happening. I quit Flow from the tray icon, but apparently it doesn't quit, so doesn't start when I try to launch it.

[jjw24]

Yep, these are the issues coming from the clipboard plugin. We will see if we or the author can sort it out. In the mean time feel free to continue using it with the terminating task work around or uninstall the plugin.

This issue should have been addressed if I am not mistaken. If not the case please reopen.

Tested on latest Flow version and no issues. @Positron010 please update Flow and if the issue is still occurring re-open the issue. Thanks
