something wrong with my javascript board; can't see squares

Hi,

I'm just reporting an issue I'm having, just as a general FYI. I can't see the squares on any board I switch to. It doesn't matter what theme I'm using.

It seems to be a problem that's local to my computer, so it's not a site issue. I can see the squares just fine on my laptop, but not on my desktop. Both Firefox and Google-Chrome on my desktop computer show a completely blank board. So I can make out the pieces, but there are no demarcations between adjacent squares, which kind of makes it hard to play.

The only reason why I'm reporting this problem is that both Firefox and Google-Chrome are suffering from this problem, which means that uninstalling and reinstalling both browsers probably won't help. I've had this problem since yesterday, so it doesn't matter if I close the browser window and restart.

Okay, that's everything I can think of saying.

Also, clearing my browser cache doesn't seem to solve the problem.
