Hi ifan,

I guess you are trying to display custom forms example on machine with aero enabled.
In this case the frame is drawn by the OS.
To be able to display predefined frames you should set UseGlasIfEnabled property of the form to CommonTriState.False.

Hi all,
i download the trial version of Nevron app , after that i see the sample in folder
"Examples\UI\WinForm\CSharp\bin\Release" then run Nevron.Examples.UI.WinForm.exe

i select "Custom Forms" on navigation tree then try choose predefined appearance like "simple,VistaSlate,VistaRoyal,OpusAlpha ... " when i click "show form.." button
i see a simple form of my original vista style, whatever the value in predefined is..
yes i already choose the "predifined" radio button, what the problem?
