If you want Google searches to go back to the modern style, you need to change your User-Agent string.
For Safari, enable the Develop Window and use an option in there that works. [crarko adds: I don't have an older system active at the moment to try this.
Once that was all done, I could log in from all my Macs, fire up the applet and establish a secure connection. I made sure that the Safari and Java preferences were set the same on each machine but still no joy.
I'd be curious to know from Mac OSXHints users whether they are experiencing this problem in the first place and if the workaround works for you, too.I sometimes find the Java setup on my various Apple devices to be a mystery.
