I prepared a Workbook at work that has several Worksheets in it. One
Worksheet has a number of checkboxes in it. I can check the checkboxes fine
at work and so can my assistant. However, another of my associates is unable
to check the checkboxes and I am unable to check them on my home computer. I
am unable to find any solutions searching here or elsewhere.

Any ideas? Help!

Thanks,
Mike
