Thanks for posting these -- I've noticed a bunch of errors in the logs and don't know where they're coming from.

For the first one -- what did you do to get all of those? Did you just post a new forum topic?

For the second one -- the images showing up through the list isn't an error so much as a quirk. The rich text editor has a habit of doing things like that. (It could also have something to do with your browser and how it handles semi-transparent layers.)
