Ok...not sure what is going on with SW..but these little error
messages that keep popping up are getting very annoying.  I did a
small change to a part that is part of an assembly.  When I went
back to update my assembly, I receivedthis error (an invalid
argument was encountered) then SW shuts down...hmmmm...I know for a
fact at the time this happened, SW and I were not arguing!!
