I would prefer something more automatic...didn't know if RP or Jay or
others could whip up something interesting.

I can't create a log, though I can do some basic checks I think.

Just says Illegal instruction at _A008 I think. The app name always varies.

Yep.

That's a strange place to

It is a living hell. Just killed me a minute ago, again (about 5 times

Goes away for weeks, then comes up again and ruins my life for a while.
