I have completely lost the ability to access the Internet and/or local network after upgrading to PD6 from PD5. My support ticket is 985706. Seems that there are some major networking issues with this release ...?!
Might be a bug with Parental Control. http://forum.parallels.com/showthread.php?t=104229 I wonder why only some people have this problem (I haven't experienced this).
Yes, noticed that too. No "fix" yet. For the record, I'm running OS X Snow Leopard (10.6.4) on a 3.06 Ghz iMac with 6GB of Ram.
