Don't panic about vince appearing to be the originator of this thread...that was my doing!!
Vince had started a thread a week or three ago, it wasn't particularly window cleaning related so I merged it with David's, but the way it got merged it ended out with Vince heading up the thread and not David
When merging a thread you have to careful which way round you merge them, and once done it can't be undone!!
There is a Gremlin in the works though, but Admin are on the case
