I have been unable to uncheck the box that allows me to show my friends where I am in Second Life. Every time I uncheck this setting in the friend's list, I am unable to even click on that friend's name. When I log off and log in again, the setting is back to being check. How do I fix this problem? The first time I noticed it was Saturday July 16, 2011. It does this on both Singularity and Phoenix viewers. I never had this problem on Phoenix before.
