Mousewheel behaviour in MIDI editor ??

Is it possible to alter the behaviour of the mouse wheen in the MIDI editor? The wheel seems to zoom horizontally in the MIDI editor, despite the fact that I have it set to "scroll vertically" in the actions list. It's driving me nuts!!!!

Hi FunkyDrummer, in the actions window there is a roll-down-menu on the right side, captioned "Section". Choose "MIDI Editor" and assign the mousewheel. HTH -Data

It's as Mr. Data says.
