Another bright note, this forum upgrade remedies the issues I have been plagued with for quite some time in Chrome involving the removal of stuff like backslahses in code / php snippets when previewing a post.
Paragraph spacing integrity also seems to hold perfectly in this version (yah!).
So if this stuff breaks down the road, I can only assume some mod or custom code re-broke this (fingers crossed this doesn't happen - I hate having to open a thread in Opera just to be able to post things without worrying about formatting / vanishing characters!).
