Objects editor bug

When you double click object in the objects editor, it opens new window (Edit the sprite object) where you can edit collision mask etc. that’s how it works correctly.
But I got this annoying problem that sometimes when you double click object in objects editor, that new window kind of opens in the back of the GDevelop window (or somewhere) and you can’t access to that window no more. You can highlight objects in the scene view, but you can’t click them (or you can click anywhere but nothing happens) and you can’t close GDevelop because that “Edit the sprite object” window is somewhere hide. So only option is to close the GDevelop Ctrl+Alt+Delete.

This happens every now and then.

I use Win 10 but also this happened win 8.1 and 7
Gdevelop version 4.0.89
