As the title says, when I try to select a single check box it will select them all. No matter which box i select it will start from the first check box and check them all in order. After all of the boxes on the document have been selected, I am unable to uncheck them.

I am using office 2010, but I am pretty sure that the document was not created using the same version. I would attach the document but it contains information that I cannot release on the internet.

Thanks for any help!
