hi all

This is the most ridiculous and annoying problem ever, in fact I can't
believe I'm about to write this but, here goes... I can't open the door to
one of my upstairs bedrooms anymore! The damned thing has suddenly
overnight become completely immovable!!?? It's almost like something is
blocking it from the other side but, there's nothing behind it that could
have fallen over or anything and I'm absolutely baffled as to what the hell
it could be that's causing it.

Anyone ever encountered anything like this before? Short of going up a
ladder and smashing my way in from the outside, I can't think of what else
to do?

cheers
