html stripped from WP 2.6 image captions?

Hi,
I am using image captions to provide a link to the photographer as a way of giving them credit. When I create a link in the TinyMCE editor it gets stripped when I save the post or switch to HTML view. For that matter, any html markup in the image caption gets stripped.

I did a bit of debugging and the html stripping seems to occur with the line:
t.onPostProcess.dispatch(t, o);
inside the “serialize” function. I don’t know where to go from there though.

Any ideas would be appreciated. Thanks.
Chris
