windows 8 is not known to cause any problems…
but I am not seeing anything wrong… what buttons dont work? everyone I tried worked… which browser?
that said, there could be some issues because of that link I gave you… this is getting loaded:
incorrectly by your wp theme or another wp plugin… it violates the wp best practices in that its loading an external copy of jquery instead of the jquery that comes with wp – a recipe for problems…
if you can find the misbehaving theme or plugin and where its loading that, we can help correct it…
but still, what I tried worked fine…
