How do I turn off the trackpad when using a mouse?
Often, while using a mouse on my MacBook Air, the cursor will jump to a strange location, thus I am typing in an inappropriate place causing confusion as to where I am in an email, document, or other application. Is there a way to stop this from happening? It is very annoying. I think it's caused by a Trackpad issue.
MacBook Air, Mac OS X (10.7.5), 1.6 GHz Intel Core i5, 2GB
