There is an annoying problem with posts containing html code samples, or perhaps anything with a less-than sign.
For example, it quite possible to make a post containing the text [SCRIPT] (with less-than/greater-than brackets). In the html view, the less-than sign would be correctly escaped as "& lt;".
However, when the post is edited, the editor loads the escaped less-than sign as a plain less-than sign in html view.
So every time a post containing less-than signs is edited, a whole lot of manual editing in html view is required.
Is this the correct forum to post a bug report in btw?
The reason that this is an annoying bug is that edits will be a definite in articles. In an article with about 10 less-than signs that you have to edit a week later, all 10 less-than signs would have to be found and corrected. If you miss 1 and only correct 9 of them, you would have to edit the post and correct all 10 again. It is not a simple search-and replace because some tags are meant to be html but others not.
I don't know what the cause is but it seems like some filter somewhere is incorrectly converting < to < when loading a post into the text editor.
Try it now, make a post with the text "<" and then edit it.
