In the screenshot below, ArcMap 10.1 appears to be making some arbitrary choices about the font to use for:
- The Layers data frame name in the Table of Contents (larger font than expected) - NOW FIXED
- The Main Menu pulldowns (smaller font than expected) - NOW RESOLVED
Can anyone tell me where to find a setting that will enable me to make these the same size as the font used for the Main Menu items, please?

UPDATES:
I finally resolved this by visiting Control Panel\Appearance and Personalization\Display and resetting the font size I had set there from 150% to 125%. This resolved all.
I was also pursuing the mismatch in font size between Menu items and pulldowns via the ArcGIS Discussion Forums.
The problem also affected the docking guides used to help resize windows (see graphic below).
