Starting today, I keep getting pop-up errors stating "hashFtrack is null or not an object".

gordon - sounds like you got something corrupt, cache, spyware or something...never heard or seen that one before. did you try blowing out cache, running spyware scan and rebooting?

Sorry for the late response.

At the time, I cleared out the entire cache, etc. - no change. Problem went away later that day.

glad it resolved....computers...geez!
