Graphics Display issue


Just wondering if anyone else is experience a similar problem. The issue relates to the screen display detail disappearing when the cursor  runs over the fly out tool bar. ( Ive attached a screen shot.

Below are the specs for my PC

Software: Inroads (latest version)

Machine spec.

i7 quad core 3.4GHz

8GB ram

Nvidia k4000 graphics card

64 bit operating system

Any help with a fix  would be great!!
