Hello Thomas,

It was foretold that on Sunday, September 1, 2002 at 10:57 GMT +0700,
Thomas F. [TF] would type:

TF> Are you sure about this? It means that the next mail will be
TF> downloaded only if the previous one has been processed through the
TF> filters;

Yup, that is correct.

TF> and if the filter calls an external program with "wait for
TF> program completion" marked, downloading must be halted during that
TF> program's execution.

That's how it works.  If you use Marck's SpamCop filters, you can see
this in action very easily.  Just watch what happens as the response
filter spawns the batch file that runs IE.

TF> I don't think this would be a very wise algorithm, that's why I ask
TF> whether you know or assume TB acts like that.

It happens all the time here.  I use VBScripts for various things and
if I change mail directories or something without updating the
scripts, I get this happening.  The script fails (silently) but
the script process continues to run, so TB seems to hang.  If you kill
the script forcibly, then TB can be "revived".

TF> Apart from that, the Connection Center would still show the running
TF> task, wouldn't it?

Yes, but it isn't obvious why the CC is stopped.  It is easy to blame
TB when it really is the external program's fault.

TF> And that task would be killable by hitting Delete
TF> or Abort.

Nope.  Try it.  Make a simple .bat script that has one line containing
"Pause".  Then run it from a broad filter.  Watch what happens when
the filter is invoked before you manually kill the script's window.

TF> FWIW there were no filters calling any external programs or
TF> scripts when the problem occurred on my box a couple of months
TF> back. The running task was definitely the Connection Center
TF> itself.

Which is why I said, just another thing to check. I've had the problem
you're describing too, but typically, I've found that to be killable
with the Abort/Delete buttons. The only time *I've* experienced a
non-killable "hang" is with a misbehaving script.

Again, I'm talking only about the current version. I will not presume
to discuss previous versions.
