Excel and .csv
Have you made sure the .csv extension is associated with Excel and that the default delimiter is a ","? I know on my system when I double click a .csv file it pops up in excel and formats it. From your display it looks like the formatting piece did not take place, it seems like it was something in the system setup. I can not remember where you set this up, hopefully someone else will know this.
I also deleted the other post - the one with the .doc attachment. My system really choked on it.
