I first thought Dick was working on the interface but 2 days later it was still there.
I'm on windows 7 under firefox so I tried on my husband's PC (7 and firefox also) : same result.
I tried Chrome - which I never use : it was perfect.
On my mac, firefox had no display problem neither (even if ADBlock is activated).
Then I had the idea to disable ADBlock and everything was back to normality. Too proud to have solved my problem alone like a big girl !
Am I the only one in that case ?
