For me at least....
Whenever a podcast is played, the screen goes black (not off, but black).... and stays that way indefinitely. This interferes with Key Lock. Plus, when PodTrapper is running in the background, and I'm on the main blackberry screen, the backlight timeout no never happens! (I have backlight timeout set to 1 minute, but with PodTrapper running in the background, it never times out!)
