I saw an old post about this same issue for Capture 16.6 that was solved by an update. I'm currently running Capture 17.2-2016 S048 on Windows 10. I have the same issue that while other tabs or windows close with Ctrl+F4, I can only close Property Editor windows using the mouse right-click menu as shown below:
Note that in this menu it shows that Ctrl+F4 should work to close the tab, but it doesn't. Any ideas how to fix this?
Thanks,
Gabor
