I can't work with Draftsight because cursor movement is very retarded. It doesn't follow mouse movement and it's impossible to draw.  I've been working with this software for a month and it worked fine!

Do I have any option to receive an old .deb version of Draftsight for test it?

I'm working with Ubuntu 14.04 LTS and Draftsight v2015.2.0.2052

3,8 GB  ; Pentium (R) Dual-Core CPU T4300 @2.1GHz x 2 ; Mobile Intel GM45 Express Chipset; 64bit SO.

it seems that works fine with windows version using wine... but I need more time to confirm!

thanks,
