Thanks for replying,

I found on borland newsgroups people supposing qmemory as borland memory
manager replacement for a long time running or a multithreaded applications.
i have use it also on my several delphi applications without problems, i
formerly was IBX user. Due to the my company policy to use firebird instead
of interbase, i try to switch to IBO. the problem does not exists on
unidirectional dataset, but for this case using unidirectional dataset makes
my application slower because I need to move backward looking for
referencial info. i found it is faster using IBODataset/IB_Dataset since i
just need a short range to move backward, re-fetch record from server is
slower on this case. and the exception raised when i try to close it (the
form), "invalid pointer operation".

I have traced it and found this problem was raised on QMemory when it tries
to release memory used. though, i haven't try to ask the author since my
previous applications works well using it, instead i tried to ask it here to
know whether there was some tricks or tips using qmemory with IBO. hopefully
i could get some clue(s) to get out from this darkness. :-)
