  1. Ryan thanks for this website/blog it is excellent. I have tried to use the examples but when i click on “Manage Add on” i get a run time error and xcelsius closes down? i am running XP with xcelsius 2008 (SP2)

  2. When I go to file -> Manage Add-ons.., the option is disabled on my Windows XP computer at work. At home, I have a windows Vista machine and I am able to manage add-ons without a problem. My user account is an administrator on both computer so I don’t understand why one allows me to manage add-ons and the other one doesn’t. Any ideas?
