It's to do with threading, each thread should have it's own
connection. If you are doing anything using a timer, and
that timer is using a thread, then I sometimes see problems
when another module is also using that connection. If you
never have anything working in the background you should be
OK. Except that IBO is also doing things in the background,
but I think the timers are safe there.

There must be something doing a refresh for the remote
copies to see a change? IBO does not know about anything but
its local copy, and it's that refresh that is not actually
happening.
