Hi Tom, Hi Chris,
see commit d964e7 which has the X11 code do the same as the iOS code. I'd
love it if someone who knows Windows would test the same thing there-on.
Also, are the "#ifndef NO_WHEEL_MOUSE" defines necessary (eg perhaps
required for WINCE) ? It would be lovely just to include the code
unadorned by the noise, or to use something less tacky such as "#if
defined(WM_MOUSEWHEEL)". Chris, can you see if this fixes your issue?
