I'm wondering if anyone has experienced some unusual Excel Behavior after installing the QuickData add-in. Here is on particular example of an unusual and annoying behavior that only happens if I have the QuickData add-in installed:

If I have a multiple spreadsheets opened and I have created a QuickData query on one of them, I lose my ability to switch between the two spreadsheets. If I alt-Tab to choose the other spreadsheet it just brings me back to the one I had on top. This happens to every user I've tried this with. We are all on Windows 7 and have either Excel 2010 or Excel 2013.

Has anyone experienced this or any other weird Excel behaviors? I'm trying to figure out if the problem is with the QuickData add-in or something with Excel. However, I don't notice the above issue when the QuickData add-in is removed.
