If your scene disappears it maybe your clipping planes in Maya and not your mouse. If you are navigating with a user camera check your far clipping plane, up the amount and see if more of your scene appears. This happens a lot with importing objects from other programs.
Hopefully that's all it is, otherwise you may have to check your mouse properties. As Roman says, uninstall and reinstall
Darkon
Red bellows of flame have blackened my stones
Convulsing my frame and cracking my bones
Hell's dragons of steel who roar in their chains
Crawl into my caves to suck out my veins.....
