From what you guys have said, this sounds like an issue with the bbcode editor.  But otherwise, I can't really figure out how to pinpoint it.  Maybe it's got something to do with one of these:
- whether you let the entire page load (could also be a possible conflict with how MyBB's task system works)
- your browser
- button's you've pressed in the editor

That's my guess anyway.  Perhaps disabling the editor in the UserCP will remove this issue, though if you do find out some consistent pattern, that would be great :)

Thanks again for reporting.
