WorkPane, 2D Drawing, and 3D Object Dissappears

[avan]

I am new working with CoCreate PE and have run into a problem early on. As I draw a 2d profile of an object the lines I have drawn dissappear. Even then, if I extrude the profile into an object, once I am done it dissappears. Additionally, say I created a square, then extruded it into a box, after leaving it to edit the current WP, it reappears. It stays there up until i put my mouse cursor over the object, where it then only displays either the wireframe or the particular face that my cursor is over. I no longer can see any of the objects I have created.

This problem is only occuring on my desktop that is running Windows Vista business. I have installed CoCreate on my laptop running Windows XP and
I have found no problems seeing the object I am working on.
Are there any settings I can change in order for the object and workpane to stay visible while I work on it?

This is a graphics driver problem. See the discussion at http://cocreateusers.org/forum/showthread.php?t=6785 for hints on how fix or work around the issue.

PS: What's your graphics configuration (graphics chipset, driver)?
