[jQuery] 1px rounded corners issue

[jQuery] 1px rounded corners issue


We're (a dev at my company and I) trying to create a white inside, white
outside, single pixel border around a block of content using the jquery
corners plugin. We're not sure of the best approach for that, but what
we've tried results in some weird artifacts on the top corners:

Any advice on how to get the effect we're looking for? This has to work
in IE and FF, FWIW.
Thanks,
Jack
