Koen,
My setup is Apache 2 with mod_fcgid running my Wt program. All my testing so
far has been on localhost, so nothing weird on the network/internet should be
able to cause the loading indicator to vanish.

I was trying to avoid getting that sophisticated but you're probably right I
should bite the bullet. WTimer looks good, I'll try that. It'll also allow me
to do a progress indicator which I was already wanting.
Thanks.

This could be because an intermediate server times out the pending
request? How does your deployment setup look like?
In any case: having your web page being non-responsive for over 40
seconds is not a good thing (and not reliable either: users may use
proxy servers which are notorious to close requests that take too long
and have no data exchange). It is better to run the command in the
back-ground, from a worker thread, and use a WTimer for example to
regularly check its status.
