Hi,

>
Thank you very much for your reply. I am glad to hear that you use Invalidate() and that you are familiar with drawing using GDI+. I just pulled out my GDI+ book from v1.0 and the author also uses Invalidate(). After your reply and the book text I feel comfortable using Invalidate().

Do you have a .NET specific book on GDI+ and if so what?
(I'm battling with nested transparent controls at the moment and just relying on the old 'Graphics API Black Book')

Regards,
Viv
