Tiled doesnt exit properly in windows10

When i exit via menu, the tileset and the object windows are staying behind.
In the taskmanager there is at least one “tiled” process left. Stopping that will stop the left overs.

I use Tiled Map Editor 2020.12.18
Windows 10 Pro
Windows Feature Experience Pack 120.2212.551.0

Thanx for your product. Fantastic. I say 42, Martin
