Keyboard + Trackball

[antiphase]

So, I'm wanting to use a separate "full" keyboard for my MBP that's running PT9, as well as my Kensington Expert trackball mouse. Both of these devices work excellent until I launch Pro Tools 9. The External keyboard gets bypassed by the built in keyboard of the MBP, and the Expert mouse becomes very very sluggish during playback, however the trackpad is just fine during playback. I figured that the sluggish performance of the mouse has something to do with the external keyboard getting bypassed though. Any ideas where to look for changing the input controls to the external keyboard in PT's?

Thanks in advance.
