after so many saves in X7 i get an error saying:

"file was modified by another user since you opened the file. to prevent losing your changes, please save the new name (File>Save AS)"
its so frustrating bc i either have to rename it over and over or copy and close and re-open it and paste it, then re-save it...

no one else works on my computer.

PLEASE HELP! TIA
