No mention of a DNS fix? *sigh...
Have any of your guys experiencing these bugs actually submitted them to Apple? They are not mind readers and if they didn't QA these bugs the first time round they are obviously unaware of them until someone tells them.
Don't think its a waste of time either, I submitted a small and uncommon bug in 10.5 and it got fixed in 10.6, I had an email from the devs to say it was now resolved. Whether this was a coincidence or not it got fixed.
Submit your bugs, rather than winging about them on a forum.
