Hi,

on File|SaveWorldAs the app window greys out but nothing happens - until I press escape. No SaveAs dialog appears. A similar issue I noticed on Insert -> AddPath button. When clicked the window manager recognizes a new frame, but it is invisible and I have to close it through the window manager to get back to the application.

Magically, when I open the model editor, the SaveAs works as expected.

I just de- and reinstalled gazebo on my Ubuntu 20.04.4 with latest patches. I'm running it in a VirtualBox VM. No error messages in the console where I started gazebo (through a launch script)

Any ideas?

thanks, GG
