Office Appliations Opening Files Twice

This is quite short and fairly simple, but I felt it needed to be noted because it stumped me for over a day and I don’t want it to happen again…

I found that when some users select a document to open from within a SharePoint 2010 library, it would bring the document/spreadsheet up twice. I was unable to find a viable solution for this within SharePoint. Evidently, they were using the 64-bit version of Internet Explorer. Which is incompatible with a lot of sites outside of SharePoint as well. Using the 32-bit version of I.E. seemed to resolve this issue.
