When I scroll through open applications using Alt & Esc. I see an open application called Message Handler. If I try to switch to it my BB locks up and I need to remove the battery to reboot it (is there an easier way to this?)

Another know what this is and why this happens?

Are you running eSpell or another program from Dynoplex? That put it on my device. It's a bit a annoying but I just avoid it.

Yup I run a bunch of Dynoplex products.. that explains it thanks!

It actually does not lock up - hit Alt+Esc again and move to another icon. This is a background e-mail processing application.
