since 2 days i had several rhino(Mac) crashes using the latest release, which happens when using zoom.
anyone on same problem?
(using a fairly common logitech mouse “corded mouse M500”)

I figured it happens when i am zooming in or out with 4views on, hovering in on one frame and zoom freely.
This used to work super smooth in the previous releases.

Now this just completely kills my mac… The beachball sometimes appears but its not even rotating.
I cant pop up the “alt-cmd-escape” task manager. I have to force-shut the Mac… its not coming back.

I dont get any protocol indicating a problem i could solve.
however. i dont loose any data on these crashes. the autosaving of rhino works flawless here.

my specs:
Running High Sierra 10.13.6

MacPro6,1
Prozessortyp: Quad-Core Intel Xeon E5
Prozessorgeschwindigkeit: 3.7 GHz
RAM: 32 GB
