i have seen this on this site (i dont use the other site you mentioned) and on amazon once or twice there. it WILL eventually load,
i have opened up another window whilst the lagging window figures out what it wants to do, then i come back to it when i see it resolve in the tab.
to contrast, i have not seen this happen EVER on skyfire which is the only other browser i use and its still not fully honey ready.
what i have done on the hanging window was to hit "X" and then refresh, that alswys gets it.
and i thought you only accessed this site using the phandroid app? ;-) im teasin' brother..
