Answer
This problem is caused by some setting on the Google Maps server. (It was not there before.) You will have this problem when your screen settings are different from the default Windows screen settings. Obviously the display size for items on your computer has changed from 96 dpi to (most likely) 120 dpi.
If you have this problem, go to the ‘Preferences’ window, and select the ‘Google Maps – Map’ tab.
Go to the slider that says ‘Size (map, font, images)’, and move the slider to the right. In most cases two ticks will do. (Move the slider to the center of the bar.)
