I downloaded a nonActiveX DateTime Picker (frmCalendar) from a website recommended by RoyUK and managed to get it to work on my workbook and a few other users' workbook. Did tests on XP (Excel 2003) and on Vista (Excel 2007) - both came out without any issues.
However a few users running Vista/Excel 2007 keep getting the error message:
"Compile error in hidden module: ThisWorkbook"
I checked the contents of ThisWorkbook and it was unchanged from before I implemented the new frmCalendar. I removed all traces of the previous DatePicker implementation which was based on mscal.ocx.
I know I am not giving a lot of information here but can someone tell me where to start looking for possible problems. Thanks.
Regards
Phil
