Thanks for the reply.
The adhesive is, as you say, a nightmare, got everywhere including onto my new Fit 2 watch ... don't tell the Mrs!!
Located the problem, the bottom right hand side of the window comes out from its mount, so it keeps coming out from the guides.
Does anyone know, apart from a scrappys that I cant be bothered going to etc, where I can purchase these mounts from?
Only thing I didn't do as it was getting dark and needed to get the card back on, was to undo the bolt and take the mount off to check it, so not too sure why, when I've pushed the window onto the mount it keeps coming out when winding the window down.
