Suddenly out of the blue when I click on an item such as a notecard giver, nothing happens. Ive tried rebooting, emptying my cache, making sure its not just other peoples items, but even my own.. notecard givers that i have assembled that work fine for others and use to work fine for me suddenly dont. Any help as to what may be going on? Is there a permissions Ive turned off on myself or something? Gigi hollysharp
