I am running 4.2 on an iPhone 4. With the latest update, I can consistently make music that I'm playing freeze when I close and enter the program using the home button or lock button while in campaign mode.

Can you give me the series of things you do to make this happen? Then I can try to figure out what it is and work on fixing it. Much appreciated!

No problem. I love this game.

Here is what I have to do to replicate the problem:

Turn on music while opening the game.
Open up the game.
Continue my game in campaign mode.
After entering some numbers into the puzzle, pushing the lock/power button will cause the music to skip. Pressing the lock button again and sliding it open to continue playing also causes it to skip again. Also, if you push the home button and then press the lock button immediately it will skip again.

Thanks for looking into this issue.

Amickley.. we're not seeing this problem here on our iPhone4. Can you do a complete reboot, update to 4.2 and then check again to see if it's still doing it?

When our app goes into the background (by tapping the lock or home button) we no longer have any control of it. The OS sends us a message to let us know we are about to resign control and the only thing we have time to do is save off the current state. Even if we tried to keep doing something we're not allowed.

So I suspect that this might be another issue with your device. Either it's just a reboot issue or possibly a hardware problem.

I'm going to email you directly about this also.
