ACP Stops on 2nd target with "Script Error (Tracking has been stopped)"

[A Michael Smith]

Hi Bob,

I've read the several recent threads with similar symptoms, but this situation seems a little different.

Here are the circumstances:
* I'm running a plan with three targets.
* First target completes with no problems.
* At the very start of the second target, ACP attempts pointing update, but fails with the following:

05:48:58 ==== Starting target N7789 ====
05:48:58 ;
05:48:58 ; === Target N7789 ===
05:48:58 ;

On similar threads, I noticed that you instructed the user to force a shutdown of Maxim. In my case, Maxim had already terminated on its own. Note that about six hours elapsed between the failure and when I discovered the problem.

Also, I have been running multi-target plans earlier this week without problems.

I'm running:
* ACP 8.0, build 5, V8 production release A
* Maxim 5.23

I should have good weather tonight if there is some to try...

Thanks,
Michael Smith
