Sub-Object Selection on Rhino for Windows on a Dual Boot Mac

Not sure if this should be in the Rhino for Mac or Rhino for Windows forum…

I have a few students who are using Rhino for Windows, but running it on a Mac which boots into Windows. It runs fine, but when trying to do sub-object selection (Ctrl+Shift+Click) nothing gets selected. We’ve tried alternate key modifiers but it makes no difference - we can’t get it to work.

Anybody have this working or have thoughts on what might be going wrong?

Thanks in advance.

I get this sometimes on straight Rhino for Windows. I have no selection window, just to do a normal selection. Possibly I have T-Splines running. I usually just close the model and reopen and it works. I don’t believe it is a Bootcamp thing.
