It's never happened with me at all, under either of my OSs, or any browser I have. I'd try using a different browser for a while. If it doesn't happen with that browser then try reinstalling your usual browser and see if it continues. If it keeps happening with a different browser then I'm not sure what you can try. It's worth testing to see if it's your current browser though, and purging your Rome.Ro cookies might also be worth a shot. I'm never entirely sure what effects munted cookies can have, but that's all the more reason to test them IMO
