> The Windows VM code explicitly disables mouse wheel events with Shift and Control, in both 7.3.1 and 7.6, and presumably all other versions since the mouse wheel was first supported. IIRC I'm not allowed to reveal details of the VM source, since that isn't in the NC version. I will however point with interest to the following piece of sample code on MSDN, which also disables mouse wheel events with Shift and Control:
>

> case WM_MOUSEWHEEL:
>     /*
>      * Don't handle zoom and datazoom.
>      */
>     if (wParam & (MK_SHIFT | MK_CONTROL)) {
>
> That code may makes sense for the multiline edit control of the sample, but would seem to be a bad idea when handling events for all controls and deciding what to pass to the image. Maybe someone would be kind enough to create an AR for this? It's been bugging me for a while too, as people have come to expect the mouse wheel to be used for zoom etc. with these modifiers.

> My Mac mouse only has one button, and my Linux is under VMWare and the mouse wheel probably isn't set up properly anyway, so I can't really test those. A cursory look at the Mac OS X source gives the impression all modifiers are passed with mouse wheel events. The Linux code is beyond me; I have a vague recollection the mouse wheel is just treated as a button there, in which case it should work.
