Hello Bill,
IF it works in the safe mode then this is because of corruption of the dat
file .
search for outcmd.dat , frmcache.dat , extend.dat , views .dat , when you
search it make sure u search after checking the box search in non indexed and
hidden files and the location should be c drive, sometimes you may not find
vies.dat it ok go ahead with the other three files

Thanks,
Yam
