i got the following problem when i clicked on a Poll option in umm…some F1 constructors championship thread…
after clicking, the page scrolled down and this appeared…however, i tried to vote again and it showed tht i hav already voted…
BTW…enable attachments at feedback…necessary to post scrshots of the prob 
try to repeat that error…
I think either you did not allow the page to fully load or maybe a slow connection. Anyway your votes been registered.
that thing appeared microseconds after i clicked on the vote button…
BTW i use FF 1.0.2 with an ok kinda connection, not too slow or fast…
hmm if it repeats inform me.
