History tends to re-enforce a belief pattern...especially when considering that NO other major browser has an issue.
Again, history also shows a pattern of unexpected things in ICT in these kind of situations where the single browser issue does not occur on other applications.
Remember that bbcode is an addon in an editor. I remember more odd things from history where things also almost seemed pointing to only 1 thing, but still was something else. And again, there is no single reason to write in caps. It won't give you any more argument value and it certainly won't change my thoughts of what is possible.
I'm too old for that and seen too much of odd things happening. You can point to that Occam's Razor theory. I'm not native English but then I point to the well known Murphy's Law which has occured enough times in ICT. It tends to, but does not need to be that way.
Next to that... if Andy can fix it that fast and easy, why can't Xenforo?
Anyway, theory is still not a fact, no problem which theory anybody want's to use, it's not proove.
We just both can't proove which one it is (which is neither my intention) so lets leave it at that, we will probably see who's
thoughts are correct in the future sometime. History is no guarantee for the future.
