More a tip than a hint: When the Microsoft Office 2008 installer tells you to shut down other running applications before installing, listen to its advice. I just installed Office 2008 and threw caution to the wind by leaving Safari open (I had a page open with an unsubmitted form that I didn't want to lose). After the installer finished, Safari seemingly lost the ability to display a significant number of consonants when rendering sans-serif fonts. Not exactly a system melt down, but it made Safari strangely unusable until I rebooted. [robg adds: As a counterpoint, I left tons of stuff running while I installed Office 2008, and didn't seem to have any font-related issues.]
