If this happens when you scroll from top to bottom ot the trackpad, please be aware that this is a stupid gesture it sends Win+D. Unfortunately there is no way to stop it, it is built in the driver.
The only way to workaround this is to disable the Win+D shortcut.
I hope this will help you.
P.S there is a thread with similar problem and some suggestions in the cube iwork10 ultimate (which uses the same keyboard)
