Hi Mia,
Let’s start with your SystemInfo.
In Rhino type SystemInfo command.
Copy and paste the text results into your reply.
I just worked with a customer that had this layer drag issue.
The problem was related to:
- His laptop being unplugged
- Nvidia being the primary display/OpenGL.
It was resolved by:
- Closing Rhino.
- Plugin in the computer to power
- Setting Rhino to High Performance as instructed by this Forum link
- Then restarting Rhino.
Always get all the updates from your display card manufactures. Windows updates do not do this. You may need to check AMD, Intel or Nvidia website and download the latest diaply drivers for you primary and secondary cards.
If any of this helps, let us know.
Sincerely,
Mary Ann Fugier
