>Not that I know of. I'm running DSL, and have the internet connection sharing for the laptop - but I'm writing this on the machine which is hooked directly to the DSL modem. Besides, this wasn't happening two days ago.

First, if you not already have done it, I would clear the cache and restart the browser. If it still occurs, I would see if you have it on another PC. If not, a reinstall of the browser might do as it might have corrupt some of its data somewhere. If you have another browser, that will also be a good test.
