William,
that's a tough one. FeFlow is currently available in version 5.305. If this is a known bug, it's pretty much guaranteed to be fixed by now (in version 5.3 that is). You could go through the bug lists at

and check if this was fixed in a patch or newer release and update your software accordingly.
Sorry, for not being of more help ... Chris
