Activex controls Excel 2007 in Excel 2003

Hi there,

I had to create a form for our graphics department in Excel and I stupidly created it using Excel 2007 when everybody else is on 2003.

The form has tons of text boxes, combo boxes, check boxes and radio buttons plus a wee bit of VBA.

For some reason I cannot exit design mode under Excel 2003 so it's quite useless. Has anyone seen this before?

Thanks!
