Here is what is happening. I just got a new laptop. A Lenovo Y480. It has a NVIDIA Geforce GT640M LE graphics card with 2GB memory. It has 8GB memory and a 3rd Gen Intel® Core™ i7-3610QM processor.
When I run this laptop with the NVIDIA card bobcad's Menu Bar (the one that has File Edit View and so on makes the whole screen flicker when I move from one menu to the next. This is only when I click on one of the item so it is open. Like when I click on File it opens up so show all the features the screen flashes. Then when I move to the next one Edit you see the Edit menu open and the whole screen flashes. I'm saying flashes, flickers or it could be seen as kind of every thing jumps a little.
Anyhow, wonder if anyone has seen anything like this and if there is a way to fix it. Kind of sucks that I bought this computer to get bobcad to run better than my old one and now I have this problem.
This computer also has intel graphics that use shared memory. When I set bobcad to run with the intel graphics everything works fine. I forgot to mention that I am running windows 7 64bit.
