I've got a Samsung Omnia Pro B7330, and am unable to run any program for .net compact framework on it.

My last three Smartphones had been HTC brand, and all the programs I tried are just simple winform apps, which ran on all HTC phones.
But not on the Omnia.

Whenever I try to start an app, I get an "unexpected error" / "NotSupportedException" at:
Microsoft.AGL.Common.MISC.HandleArt()
System.Windows.Forms.Control._InitInstalce()
System.Windows.Forms.Control..ctor()
System.Windows.Forms.Button..ctor()
MyApp.InitializeComponents()

The proper compact framework 2.0 is already installed in the rom, installing CF 3.5 didn't change anything.

Anyone can tell me whats the problem with this phone?
