in reference to:
since the handling of threads, posts and im's are handled
with id's which are NOT unique you could encounter
problems if f.ex. two ppl (or you with more than one
window open) use functions like delete or move.
example by YaBBo:
Thing is, lets say two admins, are browsing though, both
see a horrible post and want to remove it.
Admin A removes it, Admin B's window is not refreshed
yet and so they still see it.
That 'id' that Admin B is about to be use in the access
of the 'remove' button should point to a dead reply, but
it actually points to the next reply now (or it is out of
bounds), which doesn't need to be removed.
