Wierdly, the Omiga homepage has disappeared and Google looks normal again, but isn't functioning well. Some pages work, some won't. For example I can click on this forum link from my emails and it works on IE and I can post fine, but I click on other links, from my emails or even from my favourites on IE, and they don't work at all - I just get a blank page. Searching isn't an option either. My pc is also very slow for the first time today since I've had these problems. Safari is still working fine, but on a go slow. Happy days!!
