Reasonable guesses, I am sure, but I know that is not the problem. First, I don't muck with attributes on my local PC. Second, this is occuring for files that I have already opened and modified during the same session ...

Thanks, though.

>Make sure the attributes are the same for both the SCT and the SCX. If a SCT is RW and SCX is RO, no good.
