You get the clock stops ticking message when no data has been received from 
the receiver for a while. In the upcoming version the behaviour has been 
changed to a warning rather than shutting down the connection.
There are different priorities for threads in the program but they don't 
really do much. The opperating system on the phone isn't a true multitasking 
system, it has a scheduler that just runs a list of tasks. This means that 
if something takes a long time then it stops other tasks from running. 
Unfortunately database access is one of the things that can take a long
