I'm happy to hear madExcept seems to work fine for you!
FWIW, madExcept does not contain a memory manager, unless you activate the "active error search" options on the first tab of the settings dialog. Only for those options madExcept overwrites the memory manager with its own, so it can report leaks and buffer overruns to you. These features are meant to be used mainly on your development PC, though. So for the end user, madExcept does not have a specific memory manager. For that it might still make sense to use FastMM4. Newer BCB versions automatically use FastMM4, though, IIRC.
