View Ports not refreshing, scroll wheel not working, need to pan to refresh a view port. HELP!

Rhino Rhino for Windows
1

Hello
I ram having difficulty with a re-installation of Rhino 4.0. I recently had to have my computer re-formatted due to an unfortunate Windows update and when I re-install Rhino 4.0 which had been working, I developed the following issues:

  1. My mouse wheel which I use to for dynamic scrolling only works until I select any operation in any particular view port. If I pan, or tilt or select an object the scroll wheel no longer works.

  2. When I select an object, I need to manually pan the view port in order for the object to become active (yellow line in the case of curves). I then need to manually pan the other three view ports to have them update. I even have to pan the view port to use the ESC key to deselect an object or operation.

If anyone had any thoughts I would greatly appreciate the help.

I am using an Alienware Laptop with a GeForce GTX 970M video card. I am running Windows 10.

I have re-installed Rhino in Safemode with no luck. I am using the most current Rhino 4 update.

Thank you for your help
Ben

Tell us about your system.
What version of Windows 10?, 1709 or 1803?
In Windows Device manager > Display adapters, what are the models and dates for all your display adapters?
What screen resolution are you running?

Also, make sure you get the most recent available video driver for your card.

I set my OpenGL setting to match your picture and it solved the view port refreshing issue. Thank you!

Still can’t scroll using the scroll wheel.
