I'm getting an error message every time I try to maximize scene window.

Unity version : 2019.4.14f1

Peek version : 2.0.0a5

Reproduce step : Double click on the scene view to maximize it

Error message :

Invalid editor window UnityEditor.FallbackEditorWindow

Also reproduced with a clean project with Peek as only asset imported.

Hi Janitou,

Sorry about the issue and thanks for the bug report.

I have seen this issue sometimes myself, however I can't seem to figure out what causes it.

It seems like somehow the Unity window layout becomes corrupt due to maximization.

One trick that seems to resolve it is to save your layout, then reload it instantly.

Let me know if that works for you.

If you can ever pin-point any event that makes this bug reappear, please let me know, it might help me fix it!

Lazlo, thank you! That solves the issue. I will let you know if this bug reappears again, we know we hate this bug.
