Palm OS
In order to make the use of Cetus GPS as problem free as possible, some of the regular Palm OS features have been disabled as described below.
Palm OS dialogs
When Palm OS displays generic dialogs like for instance the keyboard dialog or the grafitti help dialog, the serial communication is stalled. In order to prevent this, Cetus GPS discharges the request when Palm OS tries to open the dialog. You are therefore unable to use these dialogs, while Cetus GPS is active.
Palm OS buttons
The silk buttons that are not related to Cetus GPS and unused hard buttons are disabled in order to prevent accidental termination of Cetus GPS.
