Chad,
Thanks for sharing your command button image strategy. I follow what you're doing to get your PNG images to display properly (very clever use of the image controls to "pre-render" the image correctly!) and will use a similar technique if we find a good source for PNG graphics (we currently use BMP images only).
Your software must look great! Are you allowed to post screen shots? I'm always looking for great UI's to study.
Thanks again for your help,
Malcolm
