Tested examples in ubuntu 9.10 (in VM) and if I use WindowBorder.Fixed, then window is minimal and of course, I cant resize it.
Tested by adding
WindowState = WindowState.Normal; WindowBorder.Fixed;
lines in DisplayList.cs -demo's constructor.
This may be only VM issue, but cant test other linuxes now.
(and using newest svn version of OTK)
