My experience is that doing anything GUI-related in the launch
from the paging system is dangerous, as it may be running in the pager
card's thread rather than the usual app/GUI thread. So in that sense,
you're never really the actice app in the usual sense when you get
that launch.
What I did (at the advice of Bruce Thompson) was to always
stick the message into the database, and if I wanted my active,
running app to do something, to send it a message via the alarm
mechanisim. This eliminated all sorts of strange errors.
