It could be, as ForeverYoung said, though I copied files last night and it had all night while plugged in to update the tracker...

This afternoon, I noticed is that I had used the slider to turn off the screen, and stuck it in my belt holster. when I pulled it out a few minutes later, the screen was on. And thinking back, I have had several occasions in which I turned on the screen, say to use FBreader and MediaBox was playing (generally with the FMTX on) after I thought I had paused it...So apparently, leaving media apps or even the desktop (where it was this afternoon) the screen lock is getting overridden?

Anyone seen this behavior? Know of a fix (or at least to identify the problem)?

Thanks,
