After about 10 min in grasshopper, when I try to pan in the canvas, the hand shoots to the left of my screen and my view flies across the screen until I let go of the right click. I have reinstalled grasshopper and it still happens. Rhino pans fine, just the grasshopper canvas. The only way I have found to resolve it is to restart rhino which isn't too fun.
This problem has only existed since I (coincidentally?) installed Rhino 3.0 on my computer (so that I could use bongo for animation).
I reinstalled rhino... problem still existed. I downgraded grasshopper to 5.0099 and the problem seems to have gone away. Any help with a fix is greatly appreciated.
until Rhino is thread-safe, I won't even begin to think about multi-threading. DotNET 4.0 should have extra functionality for writing threaded code, so I think we'll start investigating that when we switch to .NET 4.0
Grasshopper will run in the same bit-depth as Rhino. So if you have 64-bit Rhino installed, Grasshopper should also run in 64-bit.
C:\Program Files (x86)\Rhinoceros 4.0\Plug-ins\Grasshopper there you can find the grasshopper.dll
just drag and drop it into the rhino 5 canvas
after that you can use it as normal
