I have noticed that in this beta I am getting more entries on the DF taskbar than needed when using Office 2010. Example: Open Excel 2010 with a blank sheet and I have 1 entry. Right click on a cell to bring up the context menu and now I have 5 entries on the taskbar. This happens on all the office 2010 applications. All other applications seem to behave fine. I am running Win 7 x64 Ultimate. 3.1.7 release version did not have this problem.
