Permissions problem in Vista

Hello,

I have used, and enjoyed, Flock for over a year with no problems on Vista Home Premium. In the past couple weeks I have suddenly started to get an annoying, "A program needs your permission to continue" message from Vista User Account Control when I launch Flock. I have enabled "Run As Administrator" in the properties settings for all users but still keep getting the message. I saw a post on another forum with a Vista user having the same problem with another program. No resolution was given. I don't have this problem with any other program. I have scanned my computer with AVG free anti virus and Spyware Doctor, cleaned the registry with CC Cleaner, and uninstalled/reinstalled Flock. Still getting the annoying permissions request each time I run Flock. I hope someone will have an answer to this problem. Thank you.
