I recently upgraded from Windows XP & Vista running AUTOCAD to a Mac running the free version of DRAFTSIGHT 2016.SP1.

The cursor moves very jerkily on screen unless I have all other programmes closed and after about 15/20 minutes work the programme will freeze. The resulting FORCE QUIT means I loose all work since the last manual SAVE as AUTO SAVE doesn't work.

I occasionally get the error message YOUR SYSTEM HAS RUN OUT OF APPLICATION MEMORY

Any suggestions???
