All you have to do is delete the middle name of the person in *your* contact card where it is stored as a relationship.
I'm not sure why that works; it shouldn't, but it does.
Recently, I was trying to get a Java applet to run in the same way on 2 i Macs and my Mac Book Air.
The applet is a simple vpn client from Juniper that lets me access a Citrix Desktop from any Mac that I can install the Citrix receiver client on so I can work on 'Company stuff' from a large screen i Mac when I'm sat at home or from my Mac Book when I'm on the road (it works fine over 3/4G).
Web applets still use the up to date, secure version 1.7 plugin.
[crarko adds: I believe Oracle has said that eventually Java will no longer support applets at all, on any platform.] A few weeks ago, a number of people started reporting having trouble with Siri.
To fix things for the moment I simply removed the jdk folders.
What was happening on the not-working Macs was that the jdk versions were being used, and the Juniper vpn client won't work with them.
We respect its storied history, and value the contributions of its many readers, but we can no longer support it at the level it deserves.
Theres a wealth of great information here that many will find useful, so we've elected to maintain it in a read-only form.
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'd also like to understand why this works and why the problem even exists.
