Wow, you wrote the answer! ;-) Thanks a lot for your reply. I found it
by chance because my original idea was the site would notify me
automatically when any answer to my question would come (by the way,
how could I do it? )

JPK> you can't because the program that should restart is just crashed.

Yes, you are right.

Asking:

VB>> How can I restart the module AUTOMATICALLY after the event like the described?

I meant: (possibly using another piece of software) what is the
simplest way to make working (under Windows!) something like the
following:

Step 1  Check every TimeUnit whether the MathKernel is still Working.
Step 2  If TRUE THEN produce no action ELSE
           start the MathKernel;
           calculate the module MyModule.m
        fi

To tell the truth, I got sick and tired to jump out of bed at midnights
and restart the MathKernel, so *any* including half- and quarted-baked
ideas are highly appreciated.
        
Thank you again for you comments. 'pon my word, from now on I will check
http://library.wolfram.com/mathgroup/archive every 5 minutes ;-)

Best regards,
Vladimir Bondarenko
