It's not a cache file. It's a file right in my user directory and it even got the gif for the Cowboy Dude Ranch in there. I got 11 gif's and 2 html's in there and all have been created at the same day and time.
Plus it is getting stanger: I just checked in history what i was doing at the time the directory was created - had a visit LQorg in there at the same time but when i hit the adress to see the thread it took me to
http://survey.burstmedia.com - never been there before.
I think i got to get rid of mozilla1.0RC1 - has been acting up anyway.
