4.9.4 Windows 11 - Demo only Fullscreen - NO WindowMode

[MaTe2209]

Hi all.

We have a fully working installation (Ver. 4.9.4) with Windows 10 (22H2).

Now we have installed the PCs with Windows 11 (24H2) in one room.
Veyon works (almost) as before. Unfortunately, the demo mode now only works with full screen, nothing happens in window mode

Does anyone here have any idea why this might be!?
