Anyone else having problems editing a question/discussion they created?

Same here; if you do editing after posting and have some formatting, especially special characters * , ^, bolding,... etc, most probably some of the formatting breaks after editing. Has been like that for quite a long time.

In my view, it is not better than before.. so try to get your saying right in the first place, think twice what you post, and you will get better posts, too :o)
