DatePicker DropDown not dropping

Nov 12, 2010 at 7:14 PM

I have the latest February 2010 Release of the toolkit. 

The datepicker dropdown work great on my machine (Windows 7), but on my clients machine (Windows XP), it won't drop down. Is there anything that is not on his computer that I need to download?

Or is there a setting that needs to be set?

Any help would be much appreciated!
