I don't recall seeing if anyone asked whether you are certain there are
no memory leaks. Did you check the app with Memproof or something else?
I would guess that even a small leak over a long time could deplete
your memory enough to cause an eventual crash. Normally, I would expect
some kind of a system message from Windows about low memory but I don't
know what a Delphi app does when resources run low. Even W2000 does
not have an infinite amount of resources available. What O/S are you
running? Also, have you tried building the app under other Delphi
versions, earlier or later?
