I've been using 6.6 Pro for a few years with no issues. Very good product.
I just upgraded to 7.1 Pro for achieve compatibility with newer ACAD versions.
The computer is a Pentium 4, 2.53GHz, 1GB ram, running XP Pro V.3.
The video card is a NVIDIA GeForce 7300GT running dual monitors.

The 7.1 Pro software is a big disappointment.
First, it takes forever to load and open.
The major problem is that I am unable to view, on my screen, a drawing that I open. Nothing I have tried seems to work. I can "plot preview" the drawing and see it, but the drawing itself is not visible on the graphics screen.
I'm getting very frustrated. Is there any thing I can do to solve this issue, other than send the program back and purchase ACAD?

Because you use Windows XP, we advise you to update your graphics card driver because IntelliCAD 7.x now uses the OpenGL engine. That technical requirement also depends on the graphics card manufacturer.
Also make sure to have Microsoft .Net Framework 3.5 and Microsoft Visual C++ 2008 Redistributable.
