>Um, I think maybe you should change your thinking from "just crash"
to"exit gracefully". On a platform like PalmOS, where a crash means
youhave to find a paperclip and reboot the thing, exiting the app and
dumpingthe user back to the Launcher in case of catastrophe is probably a
betterchoice. IMHO.<BR>

I did not mean that it was acceptable for the app to crash; if there is any
way for the user to crash the program, then that's a bug and should be
fixed. I was referring to the fact that I generally check user input for
validity rather than having every routine check the state of the system.
PalmOS sort of forces you into this philosophy because many PalmOS routines
"just crash" when given invalid conditions.
ThoughtStream is still beta; crashes are a fact of life for now, so you
should keep a reset pin handy. (If your device came with the metal/plastic
3-part stylus, you can unscrew the top for a reset pin)
