E-drawings pro, files exported as e-drawings from SW2013sp3 ..  When y ou open e-drawings (32 or 64 bit) the window is free to move, you can click fine, everything works. As soon as you open a drawing though, its impossible to do anything inside of it.  You cant move the windows, cant move the drawing, zoom in/out, nothing .eventually it does whatever task you told it, but im talking 2-3 minutes later..

hard core old fashioned lag.

what gives??? anyone know how i can fix this? its just recently started doing this, never had a problem before.
