Hi there Patio,
Yep, that's what l set them to (which seems to be what they looked like
before all this started).
Have just rebooted prior to writing this and fingers crossed, it seems to be holding its own at the moment, with all icons staying where they should be.
Doesn't really explain why it was doing this in the first place, just another of lifes mysteries l suppose! Grrrr, blimmin machines!
Thanks for replying
