For now, I've no prevision date for the 0.7 release to the market place.
I will like it to be "enough" to fill the basic needs of a developer (need some feedback or use it more to see what's missing).
Maybe, it should be synchronized with an official version of fs-uae with the remote debugging option (it is not only on my hands).
So, now, I'm finishing the stack trace (call trace) in the debugger by backporting some code from winua 4.0.
Now, for your issue on windows, you may have the wrong version of the extension (fs-uae and the extension must be in sync) or a bad path in the .vscode/settings.json and .vscode/launch.json files.
Please try this :
I hope this will do the trick !
