Be careful with this mouse wheel stuff, because it is actually a real mess in the Windows world.
I am currently writing a driver for my Trust Multimedia keyboard using AutoHotkey (viz http://www.autohotkey.com/ ), because Trust's driver is just horrible. As it turns out, the usual mouse drivers send either MouseWheelUp/MouseWheelDown (WM_MOUSEWHEEL) or VerticalScroll (WM_VSCROLL) messages to the currently active control. In the best of worlds, it should be the VerticalScroll option (meaning that the acceleration behaviour is set on system level), but some applications want to control the scrolling themselves and act directly on the mousewheel events. I do not know what option PsPad uses. -- <http://forum.pspad.com/read.php?2,28655,28747> PSPad freeware editor http://www.pspad.com
