PAF4 and original release PAF5 can change Windows Small fonts to Large fonts if Edit Individual screen is enlarged beyond a certain point by the user. This was fixed in PAF 5.2. It apparently affected mostly computers with older video cards and/or computers using older non-multisync monitors.
Corrective action for PAF is to reset Windows Font to a number lower than Small Fonts 100% and reboot. If Windows does not reset to small fonts from the even smaller size, then do it manually and re-boot again.
FTM has a problem finishing the video "Painting" of its Family Page and may not show the Tabs Font. a workaround is to turn off "Video Acceleration".
UFT has many ways to screw up fonts, including globally changing some of them in Win.ini. Don't do it. Use UFT 3.1, if available. Upgrade to UFT 2.8 if you have older version. Resetting to Small fonts and re-booting may help for those users still using UFT charting, etc.
TMG 5.09 users are currently experiencing some sort of menu grey-out. This could conceivably cause problems in other older or poorly designed applications, so a check of Windows Display Properties might be in order if other Apps start acting up.
