The "running on" problem is classic indicator of software that has not been updated. I sure hope that's what it was.

However, I've recently noticed a disturbing occurance on my NXT's that have the latest firmware installed. (1.21)

While running a program, the NXT will just lock up and stop responding to all it's buttons. There is no way to exit the program, or even turn off the brick.
The only way to reset the NXT is to either pull the battery or press the secret reset button.

It usually hapens after the NXT has been running a program for several minutes.

I first noticed this while I was running a plain vanilla (FLL) NXT-G program on a brick that had updated firmware. It happened three times in one evening, on two different NXT's. I went and re-installed the older 1.05 rev and it has not happened since.

I just had it happen to me on a third NXT while I was running some Labview code for FTC.

This is a SERIOUS problem if it really is hapenning.

Now that there have been several events using this firmware, as anyone else noticed a simmilar problem?

Phil.
