3D Viewer on Windows 7 Virtualbox VM - Viewer crashes when using bends

JFuoco

I'm running Allegro 17.2 inside a Windows 7 VM on a MacOS host. 

The Windows 7 VM has the following specs:

  • 256 MB Video Memory
  • 8 GB RAM
  • 56 GB SSD

I've done testing with and without 3D Video Acceleration enabled.

Even with the most basic FlexPCB design, when I start to bend, the program hangs and eventually crashes. For example, below I tried a small bend to start, but then the spinning wheel starts up and I'm stuck waiting until I kill the program:

 Has anyone seen similar behavior? Is there an easy fix to this, or is the bend feature in the 3D viewer too intensive to run inside a VM, and has to be a ran natively?

Thanks,

Jim

    What exact version are you running from Help - About? Make sure it is the latest so 17.2-2016 S061 as see if that helps.

    Using S057 and will update later today.. But I realized I only had 1 CPU assigned to the VM. Upping this to 4 seems to have solved the problem. Thanks
