I've recently had a new PC which has Windows 7 and it seems to have messed with the display format for this forum. Everything seems to be left-justified (eg the tabs at the top of the page are all displayed vertically rather than horizontally). I remember a similar thing happening during the last upgrade and clearing cookies seemed to help then but not now. I've tried logging out, in and clearing cookies but nothing works.
It's driving me mad, can anyone help?
