If anyone can figure this problem out, then I would be very grateful. Please see this thread for full details, from the Bleeping Computer forum, where my son tried to get some help. Well, he did get some gracious assistance, but no solution was forthcoming unfortunately.

I would just add, for the sake of complete clarity, that we now don't think this is a flash problem. It looks likely that something else is the culprit. I should also mention that this issue stops the Microgaming cashier from loading as well. This isn't that annoying though, as wallet transfers can invariably be done via poker company websites.
One other thing, I have just noticed that the Poker Stars Casino and Vegas lobbies are also seemingly affected by this same issue. When these lobbies are clicked on, then nothing loads up and it's just all white space again. As with Microgaming, the actual playing of poker again isn't affected though. Thus, I am not really bothered, as the only time I ever visit internet casinos is to use free credit and free spins etc..
