For anyone who had a problems with crash at the start / beginning of drawing - try to download the new version. I found a computer with such a problem and fix it. Problem occurred because of openGL version, if so, the error will be displayed at the bottom.
I also added ability to link Workplane rotating to camera (use "cam" button at top panel) and add the program icon.
Everyone who have problems with antivirus - apparently this is beta version protector. I picked a clean program (my old game), defended it, and VirusTotal found viruses. You can calm down, this is the case.
