There is no way for a PC virus to make windows bounce around by "trying" to run on OS X, nor is there a way for windows to "resist" pop-us. Its more like when you put the wrong key in a lock - the lock doesn't "resist" the key, nor does the key "try" to open the lock, it simply doesn't work because the parts don't line up. My guess is that you have an unusual software or hardware problem. I couldn't turn up anything like that with Google. It would be interesting to know how big the "jumping" is - just a few pixels, the width of the menu bar, etc. And how fast is it? And does it jump all the time, or just occasionally make one little hop? Regarding the router, most of the pages about that box are in Japanese, so that makes it difficult to figure out what the options are. I doubt that there is no firewall for it, but figuring it out could be tricky. Probably much easier to buy a cheap little router box with a firewall than figure out how to retrofit the Buffalo. SR
