Hello! New user. First post. I am fairly new to VBA but have managed to write some very useful programs for my company. I have been using a calendar/pop-up calendar in many of my applications. I recently moved to a different computer on the same network, using the same Excel 2003. When I open one of my programs that has a user-form calendar on this computer, the calendar is normal looking for a split-second but then turns all black where I can only see today's date and many of the calendar properties (ie: Show Days, Show Title, etc.) have been changed from "True" to "False". Our IT guy says it is not a virus, but I can't think of any settings that would only cause the problem on this one computer. Any ideas? Thanks

Doug
