Mouse wheel problem Myth the Fallen Levels

[Sascha]

First of all I want to thank all of you guys at project magma for making the ;Fallen Levels' conversion, I'm now finally able to play Myth The fallen Lords (I live in Holland/The Netherlands and TFL is nowhere to be found) and I LOVE it.
But here's my problem ; I own a two butten + scroll wheel mouse and have set the 'cycle presets' command to my scroll wheel.
When I start a new game this works fine but whenever I've got a saved game and I load it nothing happens when I use the scroll wheel !
Resetting the presets doesn't help, i've tried setting another command to the scroll wheel (zoom) and it worked fine in a loaded game !?

I hope someone can help me with this problem,
