[v6 General Discussion] Scroll wheel

I use a mouse with a scroll wheel.

If I have my icon size set relatively large, so that I can read to PowerPoint slides, then when I use the scroll wheel it jumps too far. I can see slide 1 and a bit of slide 2. I select slide 2 and the scroll wheel jumps to slide 4. If I scroll back it goes to slide 2.
The only way I can get slide 3 is by fine adjustment of the scroll bar which is much more fiddly.
Is there any way of adjusting to effect of the scroll wheel or is this something that should auto adjust with the image size but isn't?

Scroll wheel controlled through control panel, I think it defaults to three lines. Maybe slides are being treated as lines.
