If creating a document from scratch, saving immediately or after changes
produces the following error: "Could not complete your request" "An Internal
Error occurred".
The error occurs after giving the file a name, and does not seem to matter
where the document is saved.
If I create a second document with the same dimensions, and copy/paste the
contents of the first into it, then I can save the second document
successfully, but the first document will never save.

FW 8.0.0.777 runing on XP SP2 with and admin user.

According to other places, FW MX had similar issues related to TweakUI, but
that solution does not work here.

Any suggestions would be welcome.

Many Thanks.
