I have noticed that every time after I install an update of Rhino 6 the Rhino Icon in the taskbar disappears.
I can only put it back there the I have restarted the PC.
This feels like a small bug to me or am I doing something wrong here?
The issue hasn’t been solved yet, and currently is marked for the future. You’ll have to make a case with @brian to have him reconsider the schedule of this bug.
