>Well I received your form and I ran it but the Sundays were not in bold on your form either. So I am beginning to think it is the _datetime.vcx class that is messed up. I tried it on my other machine that has VFP8 8.0 and got the same result. Not sure what the problem is.

You can verify that by replacing _olecalendar class with MS MonthView control but I doubt it'll help. What's the version of c:\windows\system32\mscomct2.ocx you have? On my PC (WinXPSp2Pro) it's 6.01.9782.
