bei MSTSCLib.IMsRdpClient9.UpdateSessionDisplaySettings(UInt32 ulDesktopWidth, UInt32 ulDesktopHeight, UInt32 ulPhysicalWidth, UInt32 ulPhysicalHeight, UInt32 ulOrientation, UInt32 ulDesktopScaleFactor, UInt32 ulDeviceScaleFactor)

so it die here:

https://github.com/1Remote/PRemoteM/blob/dev_net6/Ui/View/Host/ProtocolHosts/AxMsRdpClient09Host.xaml.cs#L741-L760

I dont think an assignment statement at line 753 will throw a COMException...

And since a try block here, exception should have be catched...

I have no idea how to fix this ticket based on current information.

Pending delition.

hey, what's that? you mean deletion?
