I am currently using Access 2010 in Windows 8.1 and have huge vertical spacing in the Access 2010 navigation pane. In looking through other issues of this type, others have been able to fix it by going into the quick access toolbar and switching from touch mode to mouse mode.
However, in Access 2010 there is no quick toolbar option for touch mode. As it is, I can only see about 10 navigation pane items when I used to be able to see 20 or 30. I run fairly complex databases and this is a major slowdown.
Any ideas that do NOT involve updating to Access 2013? All my other Office 2010 apps seem to be working fine - just Access has the issue.
