We have a Treo 650 with about 2MG RAM left as free memory (lots of email).

When selecting a contact to send a message to, after typing message, for instance, test - as soon as we select send the Treo completely shuts down and turns on again.

Can anyone suggest what is wrong ?

If we want to free up more room on the Treo, keeping Snappermail 2 + contacts + date book

what other of the many applications can we get rid of without compromising the general usage of the Treo - there are so many I am not sure which we can safely delete.
