A tech question. At the bottom of the screen ONLY when I am in Dreamwidth, there is a banner-box-thing that says "Do you want to open or save pibiview.js (692 butes) from ib.mookie1.com?" and then "open", "save", and "cancel" tabs. I don't have a clue what this is about and have tried to cancel it out both by hitting the cancel tab and the "X" to no avail. Does anyone know what this is about and what I should do? Dreamwidth is responding very slowly and has since this banner-box-thing showed up.
