Orbiting during surface command not working

If running a command such as NetworkSrf or Patch, I’m unable to orbit the model during the preview phase… (two-finger gesture for rotating with trackpad)

sometimes trying to rotate will do a two-finger zoom and sometimes nothing happens at all. (but no times will it orbit)

anyone else seeing this?

Hello jeff.
Same behavior on High Sierra last Rhino BETA and Rhino 5.


hmm… i’ve never noticed that before then… possibly because most of my more complex models are made on an iMac with mouse then the laptop is used for blueprints.

it’s not all surfacing commands… for instance, BlendSrf behaves properly…

…but the reason i think it’s ‘broken’ is because it works fine when using a mouse… in V5 and the Beta.
