The presentations from PalmSource 2002 talked all about extending Palm OS 5. Rather than letting you hook OS routines, the OS has the ability to use notifications to tell user code about system events and let it perform special functions. Also, if you get activated at the right time, you can override the current form's event handler, getting a first look at events before passing this on to the form. -- Ben Combee <[EMAIL PROTECTED]> CodeWarrior for Palm OS technical lead Get help at http://palmoswerks.com/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
