Hi Greg, thanks, Little Snitch is an old aquaintance that I had forgotten about! I started using the default firewall because like to keep computer systems as "default" as possible because that makes for the easiest re-install, which inevitably comes around every now and then. On Windows at least grin

Indeed these Mac problems surprise me too. My dealer told me that they have more experience with PC but that problems like this on a Mac are usually to do with network/configuration. The silly thing is that all works fine with the PWD on both Mac and PC so it seems my network itself isn't the culprit.

I take the repair permission routine every now and then. Just did it again just now just to be sure. 22 mins remaining... I'll check back in after that!

Incidentally, I also tried to install Control:PC in XP emulation under Fusion. The install went fine and the program even starts, but then keeps spinning the "connect" wheel forever. Changes to the firewalls (both Windows and Mac) don't make a difference.
