Regression: mouse drag errors? #1117

Closed internationils closed 6 months ago

internationils commented 6 months ago

I got this error dialog after clicking on the "Window" menu and then clicking in the explorer window afterwards. Able to continue after clicking YES

Do you get these errors automatically or is it worth opening a bug for them?

Fixed.

Was able to duplicate, now checking for the TV item selection. Oddly the click registers as a move operation (if the mouse moves enough when clicking in I guess).
