Thanks for the update.
The auto back ups are not at the location specified in "Options-Auto saves".
TurboCad attempts to save (becomes busy every few minutes), but the autosave file does not appear.
I run my system 24hours per day, with TurboCad active all the time, still no autosave files. A search by file name yields nothing. Earlier I moved the old files (prior to the latest update) to different directory, those files show up on the search, but no new autosave files.
