There's been some changes to device seizing in Leopard. I've had some
code of my own (albeit keyboard/barcode scanner stuff) that's been
affected by it.

I'd think that the Apple remote wouldn't be affected (unless it's
being interpreted as some kind of really tiny infra-red keyboard), but
it's something to keep in mind.

Hi,
The app I'm working on makes use of the Apple Remote; specifically,
it runs a helper app (daemon) so that the app can be started with a
press of the Apple Remote Menu button, and then passes key presses
it receives to the app via UDP messages.
I'm seeing two issues:
1) Even though I open the device with kIOHIDOptionsTypeSeizeDevice,
I'm seeing times where it seems to lose exclusivity. I can't pin it
to any specific event (i.e. wake from sleep, etc.), but it
definitely seems to lose it after a period of time (hours, days).
After that hitting the Menu button brings up both the application
*and* Front Row, which is not exactly optimal :-)
I read somewhere that if an application loses focus and then regains
it, it should reopen the device to assure exclusivity. I'm not sure
how this would work with a daemon that doesn't ever have focus in
the application sense.
2) I'm seeing cases where key-presses on the Apple Remote are lost.
It might be correlated with the actual application using a bit more
CPU. I'm not sure if the process doing the Apple Remote reception
needs to be run at a higher priority?
Any help you could offer would be much appreciated!
Thanks,
