Code mode is a feature this mod offers. So apparantly you are not in code mode.

I suspect that some of your browser settings disagree with the javascrpt that the mod uses. Since it's the image insertion as well as the auto-closing, there seems to be something amiss with every javascript driven function. Does it work with other browsers? Firefox? Opera? Chrome? Safari?

As I said, it works for me in all of the above browsers, including IE 7. No scripting errors whatsoever. If it works for you in other browsers, this has to be your settings in IE, probably securitywise/the way it handles javascript.

I do not know how this could be related to the upgrade from 2.x to 3.0, since absolutely nothing was changed in this section. The javascript has stayed the same. Sorry, but since it seems to work for everybody else (including me) and this is very likely an issue caused by the browser and it's settings, I may not be able to help you there.
