We have a XP Professional SP2 Running XP Office Professional Running SP3, It just started (1) day ago. When you go to open a doc from "file open", you get a freeze in the "Open Dialog Box (not responding)". This is true for Word, Excel, Access and also from Outlook if you try to attach a file. On Thursday Afternoon we deleted Temp Internet file and installed about 850 fonts. Friday is when we started receiving this problem.
