This is a known bug that affects users with a high resolution display.
During installation, Windows 7 installs a larger font set which is 125% of the normal size. If you then choose go back to the standard font size (100%), Windows will keep some of the large fonts even though everything else is adjusted for standard fonts, causing some programs to display incorrectly as the DPI is too big for the window size.
