See, I did that; that’s what I was talking about in the OP.
I’d been setting the increment to 1 and 0.1, because 1 was reasonable in the L/R/T/F/etc windows, but was lightspeed in the Perspective window, and 0.1 was a crawl versus reasonable in the Perspective window.
However, doing a little experimenting, it seems that, when zooming in the Perspective window, the problem seems to be dependent on which objects are visible; if a smaller object is the only one visible, the wheel-zoom in Perspective starts to get reasonable. Rather than always zooming the same amount, it seems to be proportional to the scene. I hadn’t realized that.
Still annoying, though; it’s most certainly not how I’d like it to behave. The amount of zoom in Perspective ought to be exactly the same distance as in the L/R/F/T/etc windows, darn it.
Know of a way to fix that?
