on-the-way

I'm using a standard PS/2 scroll mouse called an Intellimouse. I checked settings, even replaced the mouse and driver. Scroller works for everything else except GR. Was playing single player yesterday and half way through a mission it just stopped working. Thanks for any help out here!!!

Why would my mouse scroll wheel suddenely stop zooming in and out?

I am new to Ghost Recon multiplayer action. When I go to a lobby and click to join a game, GR starts. If there is a reason why I can't continue I have to shut down GR and retunr to my desktop. Is there a way to run GR as a window and minimize it or do something to spped up the loading process everytime a new lobby is entered? Thanks.
