Hi I've proposed a little PR to add this requested feature: https://github.com/inbucket/inbucket/pull/375
It is a consequence of the **PuTTY 0.75** big bang version. I had to remove the [TuTTY color pacth]](https://www.9bis.net/kitty/#!pages/0.75.md) that could be merge anymore in **PuTTY** source code of **KiTTY**....
Very strange: it works perfectly on my side. With ``` [ConfigBox] dblclick=start ``` in `kitty.ini` configuration file the main window remains opened after double-click on any session name. Need more...
Ok I understand: you use "Portable mode" ! I never use it. I need some more tests.
Do you try the feature [send standard output to clipboard](https://www.9bis.net/kitty/#!pages/StdoutToClipboard.md) ?
Did you run the command `kitty.exe -fileassoc` as it is described in [File association page](https://www.9bis.net/kitty/#!pages/FileAssociation.md) ? If yes, can you check the content of the registry key [HKEY_CLASSES_ROOT\kitty.connect.1] ?
