Hi, for those interested in this things:
the problem was that I was trying to Release a TForm on the DllProc
when Reason was DLL_PROCESS_DETACH. Apparently this caused a leak
because the Release method returns before the Form is actually
destroyed (maybe the dll was freed before the form??).

Thanks to all again
Eduardo
