Its close but it seems to be doing a union rather than a left outer join
(I think!).
On my sample data I have 5 'males' per 'teacher' then the query returns
a count of 25 rather than 5. Gives me an idea though so I will have a
play around with it before I go home tonight.
Thanks,

Exception "Error Creating Window" is often caused by lack of memory at the
moment of an attempt to create a window. Why is it that this exception
message is still shown even when code like that is used:

tmf := TMyForm.Create (Application);
except
Application.Terminate.
end;

You could get the Kernal Toys for Win95 from the MSDN site and see if this
points out any problems - can't remember if this includes anything to check
for system resources, or the URL.
You could also try some memory/resource debugging tools.
eg MemCheck on the Delphi Super Page - freeware. (memc
Use NT for development, it is far better at handling application errors, and
is not prone to running out of resource's like Win9X development platforms
are.

Bugs ? in my program ?? :)
Unfortunately I have the low resources situation I described the very first time I run
my app. I do have one form with many tabs and a large number of controls which may be
the culprit. Otherwise, yes, I'd expect to slowly run out of resources over time

If you Break/Reset your program from within D3, it does not cleanup/release
all the system resources eg I presume these are things like window handles,
file handles, memory.
The other thing is bugs that do not release objects created in your program

My development pc runs out of system resources (and eventually hangs) when I have my
