hello,

I just installed this software (draftsigh last version) on my HP "Pavilion dv7" under seven 64bits. The installation is apparently well done, unfortunately every time I use a drawing tool or load a file dwg, nothing appears on the screen!   Yet the lines are there but invisible (it realizes this by making a catch) ...... As the message above I checked the updates to my drivers, everything is up to date, this PC has only a small month commissioning ...

I tried to change the background colors no result. I removed aero and made a classic theme, anything either ..... My card is: Radeon (TM) HD6490M, current resolution 1600x900 60hz refresh rate.

Do you have an idea of the problem?  

 Thank you in advance
