no problem mate - as i said, i had a lot of problems with all that kind of stuff before which is why i looked into it so much
with regards to party being on your computer - this looks like something a spysite might do. They would hijack your internet explorer (which by the way is the easier browser for hackers to get into - use opera or mozilla instead) and add their party button - i bet you that the party icon has some guys affiliate code in it. If you could find it out you could get that guy in a lot of trouble - well at least get party to look into it
oh and ive said this before but only use internet explorder if you really need to - its probably the worst browser available. Basically, IE is better for certain developers, they make it so that its easier for things to integrate with it....however, this also means the mysearch assholes etc can hijack your browser as well. Ive been using
www.opera.com for years and love it - nothing can hijack it (i sometimes use mozilla as well)
