Scroll wheel zoom is unmanageble There seems to be no way to limit the speed of the zoom using the scroll wheel.  It behaved better after selecting 'auto depth' but after a restart even that had no effect.  The zoom function is a major navigational aspect and needs to be more refined.  Is there some setting or feature I'm missing here?
Had the same issue recently on Windows. I usually use Linux, but opened a file I'd been working on in Windows, and the scroll wheel zoom was WAY OFF! 

Basically, with the panel in focus, hit the "Home" key. Found this answer HERE.
