Strange happenings with screen display - help please!

Hi

I'm getting a strange layout when I try and access horse races. Everything is ok when I log in, choose racing, select GB, meetings appear on the left as usual, I can click on each meet OK. But when I try and see details for a specific race it seems as if it is way too big for my screen. Everyting is hanging off the edge/bottom and text is overlapping in some places. And I can't click on the "back", "lay" buttons etc as there are no coloured shaded areas as usual.

I'm using a laptop with a screen res of 1440x900 which has been fine before.

Any help/suggestions gratefully received as this is very annoying and I can't place bets! :-(

Thanks
Loz
