an issue i have on a regular basis is the popping of the camera view when zoomed into a detail.
sometime i need to zoom closer and then orbit/rotate around the area to grab another curve, however ive found when im zoomed in and try to orbit it snaps the camera all the way back out of the zoom and i loose where i was.
this seems like a bug. id expect to be able to orbit around when my view is closer to the model.
