Hello,
Thanks for the bug report, that's something I haven't come across before.
What mouse are you using? I don't really want to add random fixes without being able to reproduce it so I'm slightly wary of this code at present. The MSDN page for WM_MOUSEWHEEL
proposes a slightly different solution to what you have implemented, but regardless of the final solution I'd still like to be able to repro it first. I use similar code to the (original) delta code in other controls without custom wheel processing too.
Many thanks for taking the time to log the issue and propose a solution.

Hi,
I had never come across it before either until I started using this mouse. The mouse I am using right now is a Microsoft IntelliMouse Explorer (Model: 1004) (Was previously using a Logitech Performance MX but I need to get a replacement) but as far as I know it is any mouse that has a high resolution/smooth scroll. I have found doing a search on Google for "High-resolution mouse wheel" brings up information.
That fix is for when cannot do partial or per-pixel scrolling. So another way could be to change ProcessMouseZoom so it can do smaller increments using the delta.
A crude way to reproduce the problem for testing would be to change the incoming delta values to a factor of 120 (will need to handle multiples aswell). This will simulate the problem for the mouse you are using.
This will work (I have tested it with my Logitech Performance MX and it reproduces the problem):
int delta = 30 * (e.Delta / SystemInformation.MouseWheelScrollDelta);
spins = Math.Abs(delta / SystemInformation.MouseWheelScrollDelta);

Hello,
Thanks for the follow up. I used to love my IntelliMouse Explorers, they were good mice and I still have a couple of receivers still floating around after the base units themselves gave up the ghost. I don't even think you can get them now, just as difficult getting Comfort Curve 2000 replacements.
I'll take a look at this as soon as I can - I've been working on and off on a newer version of the control for some time now, should probably do some more work on that!
