Problems with screen update using RS 5.15 under Win7

When I use Robotstudio 5.15 on my Win7 Laptop I have the problem that the screen does not update. Example: I change Rapidcode but can not seen what I type. Only when changing Window size or minimize and reopen, Changes are displayed. Same happens when opening/closing the task-tree.
Same RS release on my Desktop PC (Win7) runs fine.
Any suggestions how to solve this?
I already checked for latest Graphicdriver.

Best regards.

Hmm, strange problem. Have not heard of it before. What PC are you using? Does it have built-in or separate graphics card?

Its a Dell Vostro Notebook and as far as I know its a onboard graphics.

Can it be some setting in the energy management and how do I change it?

You can always check Control Panel\System and Security\Power Options and select “High Performance” to see if it makes a difference.

I found an article that may or may not be related, see http://denis.doublebuffer.net/lablog/2012/11/19/fixing-the-screen-flickering-on-a-dell-inspiron-n5720-and-maybe-many-others/
