Marcello, (and probably other Mac-Intel users)

It is my understanding that Mac-Intels are pretty much compatible with= anything x86 based. Your problem may reside within the precompiler defines= and the libraries. The usual culprits... I know it seems obvious, but I ha= ve learned that we often need a reminder of the simple stuff.

Cheers,
