What to do when the ABCLIENT crashes

[kristan]

I'm currently trailling AbTutor and have been impressed with it so far. Thanks Andy!

We did run across a few bugs though in our testing. It seems the ABCLIENT service crashes when more than one tutor control machine is viewing it at the same time. I'd prefer if it just stopped sending to one or the other of them and continued gracefully.

What I've done as a workaround is setup the Service Recovery settings on failure to Restart the Service (Control Panel->Administrative Tools>Services->AB Client Manager->Properties->Recovery Tab).

On another aside, is there a reason that the AB Tutor Control window loses focus when we go from watching a few machines to returning to the main program? Or why the "Watch" window sometimes locks up the entire system and requires me to 'end task' the whole program?

Thanks for these comments. It should be possible to monitor a client machine from 2 or even more Tutor Control programs, but as you can imagine, the machines need to be fairly powerful to cope with the demand and the machines hardware can play a big role in whether this functions well (e.g. graphics cards, memory and network cards etc). We didn?t want to restrict the system to only allow 1 tutor to connect at a time, but maybe we will add something to enable single connections only.

Your work around of setting the ?Auto Recovery? for the Service is an excellent one and we too have recommended this to users who have had occasional client problems.

The Watch window looking up is quite a concern to us and we will investigate this. If you can reproduce this problem, can you please send us as much detail as possible so we can try to reproduce it and subsequently fix it?

Thanks, Andy
