I've disabled all of those options, yet CMP simply won't complete the scan (even w/ fastscan!).

Hmm. I'm starting to think that having the cab files in an unzipped directory is a significant inhibitor. Has something happened to CMP in the last 2-3 months that might have made this problem worse? It never used to be this slow w/ uncompressed files.

All my MAME roms are zipped (single) and are audited very quickly.

Thanks as always.
