>I'm sure I saw somewhere a setting to change the amount of scroll when the mouse wheel is turned. Darn if I can find it now. I have a very tall screen that needs a lot of scroll and it's way too slow right now.

Never fails. Once I put up the question I find the answer. It's the the VScrollSmallChange in the form's Layout. I upped it from 10, the default to 100. The form contains rows of images that are dynamically added so it can get quite tall and the 100 setting did the trick.
