well.. the following code is probably better (passing 0 may lead
to unwanted effects).. :>
MenuEraseStatus(MenuGetActiveMenu());
the reason? the Palm OS backs up the area which the "Copy"
string is drawn to.. when the command is finished.. the data
that WAS behind it is redrawn.
if you write to that portion of the screen, then you must
restore it before you draw to it.. and this function call
does this.
the OS performs the MenuEraseStatus call AFTER your
event handler is done :>
cheers.
