[D] JavaScript "Invalid Argument" Error

[Ddraiggoch06]

At first I though this was just my forum, but I have tired several other MyBB 1.4 Gold forums all with the same result (except this forum, which uses different SVN files). When you use Internet Explorer (not sure every version, but I use version 7 to get this bug) and create a new topic, click on the thread subject field, then click inside the message editor. You will then either get a dialog error similar to the one attached, or if you have debug messages enabled, the "Done" text in the left hand corner will change to "Error on page". Clicking on that preduces the same dialog error box. It shouldn't be like this, and while it is flawless in my main browser, Firefox, IE being the annoying bugger it is has to produce this message. Thanks!

Same here, just in IE7 though FF3 is fine. I get the same error on this forum too.
