Hello Maria,
Maria, I am sorry I didn’t realize you were still using Windows 2000. I resumed support for Windows 2000 SP4 on RC3 because of some feedback from Windows 2000 users. However, the only 16 colors and True Color bitmaps are supported now. 256 color bitmaps are not support any more. There always have been issues developing 256 color bitmaps, and as we need to add more command buttons to toolbars, we dropped the 256 color support altogether.
Please let me know if you have further questions.
Thank you!
