"Doesn't do the job" as in "Doesn't send a message",
or "Doesn't cure the hang" ? As far as I can tell,
it cures the hang, but I have never seen any
message from the installer that I can recognise
as such, so I do not know if any of the versions
have ever successfully produced a message on
my system. What format would you expect the
message to take, and in which window should it

Well, I have no wish to place any unneeded load on your time,
but equally I do not have any evidence to suggest that my
Windows installation is defective : the most recent error
reports were all from the live system, because having
proved in the VM that the hang did not occur, I needed
to get back to trying to find out why it /did/ occur
on the live system. I think it is fair to suggest that
if SendMessage can cause a hang on my system, it can
cause a hang on others, and therefore we should try
to identify the cause and eliminate it. To support
this, I think it is clear that Microsoft would not
have gone to the trouble of writing SendMessageTimeout
if timeouts were not expected to (a) occur, and
(b) cause problems.
