The timeout parameter of EvtGetEvent does not guarantee a nilEvent to be
generated every timeout ticks, only that a nilEvent will be generated IFF(if
and only if) no other events have been generated after timeout ticks.
That means you could either
1) decrease timeout to increase the possible frequency of nilEvents or
2) (AA's suggestion) check to see if its time to do your periodic function
every time an event is generated and just use EvtGetEvent to make sure an
event is generated every timeout ticks (so whether its a nilEvent or
PenEvent, etc. your function will fire)
I use #1
Poser does generate more nilEvents than an actual Palm device. IMHO I like
it, it helps to debug my nilEvent handling.
The UI also uses nilEvents to 'drive' some of controls so don't return true
if you do handle the nilEvent (it could temporarily mess up the UI)
was that kind enough? ;-)
