Thanks for the explanation.
Yes, it has to maintain a constant connection or the other end will log out
requiring the Palm to perform a lengthy re-login.. Unfortunately I do not
have any control over this. The timeout may vary but for the most part its
over 5 seconds. No communication for 5 seconds and a logout could happen.
This shouldn't be a problem as most people don't hold controls for more than
a few seconds at most. But it just doesn't make for a clean program if this
problem is looming, just waiting to happen.
I'm not very familiar with the whole trap thing but I will look into your
suggestion. Thanks.
