Hi Anon,

I guess too that the c-code won't be Perl-specific, the problem is that I am! I tried to get a simple screen display with Code::Blocks, but no joy. It's just too long since I had to deal with a compiler error!

Anyhow, I've stumbled through the wxPython equivalent, which gives me the same problem, so I guess it's a wxWidgets core problem. Even a totally blank window with no title-bar doesn't work, and it inserts a title-bar. I'll log it on their site.

Thanks for all your help.

Regards

Steve
