Hi MarkkuM, thanks for making the video.

One of the things that you're doing in the video is that yes you're going to a different view but you seem to be moving your mouse frequently to the exact same elevation level as the curve. That won't really work because that's trying to make a zero height extrusion basically.

Maybe it's being somewhat sluggish to respond - what happens if you move your mouse in a side view some a ways above the curve and then just take your hand off the mouse and let it sit there for a couple of seconds, does it finish then?

Are you possibly doing a right-click as your final click instead of left click?

What happens if in the last stage of Extrude you type in a distance value like type in 5 and push Enter, does that produce a result or not?

It sort of looks there like things are running well in general, but maybe there is some kind of performance problem with inter-process communication, do you have any kind of system level stuff running like virus checking systems that might be slowing things down?
