it happens to me too. save a dll file though but not on yahoo. it's ebay.
occassionally though when i try to key something on the search box and press enter, the save a file of dll pops up.
Every where i click, there will be a popup asking me to save a file earilier. The problem is resolve now. Important thing is to warn user dun ever save tat file or else chances is you will rec'd a millionaire credit card bill next month. Suspect their server is hacked earilier. :sweat:
