Commented Unassigned: avalondock invalid window handle [22233]

Hi, my tester is getting such an exception after having the app longer time in background:

System.ComponentModel.Win32Exception

Message:
Neplatný popisovač okna ------> it means "invalid window handle"

NativeErrorCode:

ErrorCode:
-2147467259

TargetSite:
IntPtr GetParent(System.Runtime.InteropServices.HandleRef)

Source:
WindowsBase

HResult:

it is perhaps corrected in the 2.9.0 plus edition. is there some solution for the community edition?

Thanks, Ludek.

In particular. We get this if the application is running and the user accesses the machine it's running on via remote desktop. This only occurs if the machine is on Windows 10, OR Windows 7 and has some sort of desktop management software installed (eg: DisplayFusion).
