I opened the app store yesterday from my applications to browse the store and it showed I had 3 updates. When I looked I had 2 from previous purchases and a third free app that I never downloaded called Itsy. It's a twitter app. Since I don't use twitter I wouldn't have downloaded it. If I click update, it wants me to log into another persons account to update it. I have no idea who's account it is. I searched in spotlight for Itsy but nothing shows up. Looked in itunes, applications folder not there. Does anybody have and idea as to why this is coming up in my account? I am the only user on this mac so can't figure out why I am getting this update. I contacted support and explained it but all they told me is to go into itunes and delete the app. Obviously didn't understand me as I did say I never downloaded it and it's not on my computer. Am using Snow Leopard 10.6.7. Thank you.
