Might consider switching to Firefox, I consider it the better of the two browsers for alot of reasons, including plugins, stability, and security. MSIE 8 which is finally in release is dog poo just like their version 7 so even on the Windows platform alot of folks are using FF. In the Mac world Apple focuses on Safari since it's been that way for years contractually plus the iPhone and other PDA's support it. I find in my web log stats more people using FF than Safari on the Mac platform, so I'm not the only one who feels this way and recognizes the differences.
Just a suggestion if Safari keeps doing that to you.
