Hi Mario,

Memory and graphic issues are quite strange under windows. Sometimes Windows API calls fail

when the images are a certain size but this sometimes depends on video mode and operating

system. I would guess that your image is fairly large and maybe in true color. There are

some comments on related issues on EFG's computer lab,

http://www.efg2.com/lab/Graphics/VeryLargeBitmap.htm

If you want you may email me the file; I can try it out, but usually I cannot do much as

there error results from a Windows call.

Best regards,

Michel
