Date and Time Picker issue
 

I am currently using Excel 2007 on a windows XP pro OS. I am inserting a DTP
control into workbook, the control works until I close the workbook and open
it again and the control is replaced by a red X and the control no longer
works. My system originally did not have this control, I downloaded the
mscomct2.ocx and registered it to have access to the control. Any ideas what
may be happening here? Thanks for any assistance in advance...
