We have a Word form for submitting requests to get some code run. It uses checkboxes to specify schemas and environments for the run.

Some users are not able to check the checkboxes. Clicking the checkbox selects it instead of checking it.

I am using Word 2013, and the form works correctly for me. We have both 2010 and 2013 users in our workspace, but one of the people experiencing the issue is another 2013 user.

Is this a Word configuration issue? Has anyone seen it before and solved it?
