Sergey,

Thank you very much.
I will try the resolution in the morning.

>>The user can click on a date to select it or scroll backwards and forwards thru the months.
>>The control used to work OK as long as we did not deviate from the standard VFP error handler. In other words, no 'on error' statement in the application.
>>As soon as we placed code for our own error handler in the 'on error' method of the form, the scrolling back and forward causes an '0x80020005: type mismatch'. The 'method' of the error appears to be 'GetDayBoldEvent' although we are not using that property.
>>If we replace our own code with 'On error' the scrolling works OK again.
>>Is something happening in the OLE black box that I am not aware of?
>>TIA!
