Hi GeneGuy,
Just to double check those folders don't exist, they would be located at:
Hard drive -> Library -> InputManagers
and/or
Hard drive -> Users -> Your username -> Library -> InputManagers
(Spotlight on OS X 10.5 won't look in these locations by default, but I think you're using 10.4, right?)
Assuming neither of the above are present, the first thing I'd try is to trash the Safari preferences file:
Hard drive -> Users -> Your username -> Library -> Preferences -> com.apple.Safari.plist
If that doesn't help, try resetting Safari via the Safari menu -> Reset Safari... option. Be careful NOT to check the item 'Remove saved name and passwords' otherwise you'll have to reenter them all...
Good luck and let us know how things work out!
