The Intellipoint software for my Microsoft mouse scrolls desirably using the scroll wheel except in a couple programs, one of which is Adobe Acrobat Pro 9.1.3. In that program, while viewing a pdf one whole page at a time (non-continuous & zoom < 100%, usually), a WheelUp or WheelDown might not be enough to go back or forward with the pages. One AHK workaround would be to send {PgUp}/{PgDn} or {Up}/{Down} keystrokes with wheel hotkeys. However, this has a bad scrolling effect when viewing pdf's as continuous pages (zoom > 100%, usually). Acrobat does well when it adjusts the scrolling interval itself, but Intellipoint seems to override it.

Sending WheelUp or WheelDown via AHK and using different send modes does not fix the problem. I wonder then how I could use AHK to send clicks to the scrollbar above or below the scrollbar cursor (or to the up/down arrows above and below the scrollbar), respectively. I tried using SendMessage for vscroll, but it didn't work at all in Acrobat.

Any suggestions to override Intellipoint for wheel scrolling?
