Can not view what I am drawing.

I am having issues with Draftsight on my desk top pc. Everything works just as it does on my laptop, except i can not see what I am drawing. If you draw anything, You can mouse over where the drawing should be, and the 'end points' and 'midpoints' show up. It is like I have black lines on a black back ground.

I changed the background color and the line color.

I renamed the "profile folder" (as recommended in previous posts) to restore Ds settings.

I checked for display driver updates (per previous posts). 

 

I have Ds installed on an Hp with an Intel i3 processor, win7.  I have an Nvidia Ge force 9400 gt graphics card, and an acer 23" monitor.

Display settings are 1920x1080, 59 Hertz with true color 32bit.

I use this machine for Adobe Light room and Photoshop.

Any help would be appreciated.
