Hi,
Something in my display settings seems to have changed, and I can't get it working normally again.
Spacebar + F doesn't focus on the selected object anymore - I need to do Spacebar + G and then Spacebar + F. Also, the wireframe disappears when I'm too close to the objects, even though the geometry still appears. There's all sorts of other weird quirks that suddenly cropped up, and I've of course tried "Revert to Default" in the display options, but that hasn't helped.
Is there some other way to reset Houdini's settings?

The viewer clipping plane probably needs to be adjusted manually. The automatic settings work okay for drawing a simple shape like a sphere, but get confused in anything more varied than that.
