Hiders (and quotes) not nesting is a known issue caused by the code stuff for it being very simple and in need of upgrades.Dunno what's up with some hiders in a post working and others not, that's a new one I think. Can you link the thread so Mahz can see what you're talking about, or maybe a regular user could possible take a look and figure it out?

Right ok thanks Jorick. And I am as regular of a user as they come :rollin 
Genuinely cannot spot the problem after considerable time looking.
