I've been getting this error lately (once per day or once per session): MAPISP32 caused an invalid page fault in module SHLWAPI.DLL I close the error message window, and keep using the system as if nothing happened. System seems to run fine without mapisp32 (unless it's restarted again?) Mapisp32.exe (version 5.5.3121.0) is in a strange location: \program files\common files\system\mapi\1033\95 SHLWAPI.DLL is version 6.00.2800.1990 xpsp2.090827-1539 Is this related to using outlook 2000 and/or
