I get "you are out of application memory" message periodically since i installed new DraftSight (2015). Older version had no problem. Mac: OS X Yosemite, 10.10.2. 16GB memory. 2.2 GHz intel core 7i 
Please, HELP!!! School paper due in a few days!  
Tried so far: reboot computer, reinstall DraftSight, quit all other programs.  

PLEASE HELP!!! Can't work with the new version!!!
