No I doubt it's a resolution issue as it is drawing the startup screen and it is drawing the toolbars in the right spot. It appears to be failing to draw the map and the icons on it. Maybe a graphics RAM issue. I note from your DXDiag report that your on board Intel graphics only has 1 Gb of dedicated graphics RAM. It shares the other four gigs with the cpu. There does not appear to be any other graphics card. However, I really would have thought that 1Gb was enough.
Can I ask you to do the following.
- Reboout your machine.
- Do not run anything else - ie do not open any other app.
- Launch CO2
- Report back on whether it works.
If it doesn't you could try shutting down processes (if you know what you are doing). Depending on your system config you could be running a number of processes in the background that are hogging your graphics RAM. But if you don't know what you are doing, then don't bother with this.
Try this and get back to me.
