Posible Bug or "FEATURE???" report...
Post editor seems to go a bit nuts and hang for longer than it should be in the posting save process?
Possibly due to length of thread? Not noticeable at first, but it caught my eye tonight.
It could be a feature or it could be a badly programmed search tree.
Either way you might want to run some tests or keep an eye on it if you are still evaluating the software.
