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.
