SW is talking back to me - !!! This has just started to happen - as i move my mouse arnound the model and edges are highlighted, there is audible beep as each edge flashes red.!!! Is this something new or have I just turned the volume up on my speakers too far ;-) TTFN Jonathan I think I am going mad - off to Brumm tomorrow - to see the modelling show and perhaps pick up a cheap Rover !
