Since R1.4 or one earlier DraftSight on rare occasions gave an error message while saving a file. After that the file was deleted from the directory and I could not save what was on the screen. Error message just read that the file does not exist. I could not save as or anything else. Now since R2.1 it is happening almost every time. Anyone have an answer to this one? I have seen similar posts but no answers to them. Reinstalling etc. has not helped. I am running Win7, 64bit and currently I am back to R1.4 and so far it has not deleted anything on me. Thanks in advance.
