Remember, I and no one else in McNeel has seen this, so we a lot of help here. You need to be excruciatingly precise in your description of how this starts. I can think of lots of ways to activate a command - a tool palette button, a toolbar button, an application menu choice, a tool palette menu choice, typing a command, using a screen edge macro, using a mouse button macro, and there are even more. All of these are going to affect that transition when a command starts.
So, please be excruciatingly precise. What command, how, etc. Did you move the mouse at all? Include every detail that you think is not important. Use this article as a guide.
Be sure to post your OpenGL settings as mentioned in the article. This also lists the other input devices you have, plus any third party plug-ins that might be interfering.
We won’t be able to find and fix this until we can reproduce it.
I think I can state by now that in my case the disappearing cursor phenomenon has gone away since the installation of OS Maverick and/or the latest Rhino version 487! (and I am still using my Wacom tablet…)
Found this thread, same problem,
the cursor disappears at random for my co-worker and myself.
I’m new to Rhino and he’s been using it for awhile.
We use the F3 command to refresh and it returns.
We both have wacom tablets connected. Our Macs are on a massive corporate network to servers and phones.
Just uploaded the new Rhino release and it eventually happened again while trimming a solid w a curve but it can happen anytime.
Thanks

More details of what just happened. The cross hair cursor in the view ports was visible but dragging outside the view ports it disappeared then reappeared again within the view ports. The tool pallet would highlight by the bounding box but there was no cursor visible even when dragged beyond the interface to the desktop but would reappear in the view ports. Thanks
I think this is a Wacom / OS X Mountain Lion incompatibility. Once Mavericks was released, the complaints about a disappearing cursor stopped. @nurd, you are still running on OS X Mountain Lion. The fix seems to be to upgrade to Mavericks.
