I have been using DS for several years and since the reinstallation of the software by our IT department I have been experiencing problems with slowness on zooming and moving the drawing in the file. It's really slow down and therefore super boring to work!
"Draftsight 2015 is no longer compatible with Windows XP
A little info for those who use Draftsight on Windows XP, the new Draftsight 2015 release (VR6 for windows32bits) is no longer compatible with this operating system. So if you download it, you will get an error message and it will crash your VR5 version: so you will have to recover the .exe if you still have it and then the layout of your profile if you had made one. So keep the VR5 release if you're on windowsXP ;)"
