Seamonkey 1.1.9
noscript plugin but alla is in the whitelist. No other plugins.
Its been an intermittent oddity for awhile, if I mass green arrow then 1 person out of the bunch has the green arrow stay and appears to have not received the rate up. If I spam click it, their post vanishes right off the page. Refreshing the page brings it back but still shows as not having been rated. Usually I leave for an hr or 2 and then when I come back I can rate it up. Really weird.
