you could re-map the keyboard txt button to something that does not bring up the txt program exiting you out of the current text message or e-mail reply.

I don't have the cab but i have used the oem when cooking in the kitchen. No2Chem has a program out that adds mapping to those buttons. Instead of just having the long press end key as a mapped button you can map the QWERTY txt, QWERTY email, QWERTY comm manager, QWERTY net, power (long press).

They show up in the start > settings > personal > Buttons
