I usually use just *one* account, it is an admin, and i haven't reinstalled
the OS. I also didnt knowingly overwrite the profile (situated in "documents
and settings"?)
I also tried the operation on the administartors account - with the same
effect...

no, I didn't - neither nor.

yes, I also have tried it with the DOS-command cipher. but the problem is
the same - when cipher accesses a ciphered file, it too hangs up...

my encrypted folder is *only* user data (containing .xls and .doc).

any help????
