well I seem to have solved a problem, the 'g' key wouldnt work if I used the shelf (in window) shortcut symbol. If I chose move and sew from the drop down menu it worked fine.
I could be wrong but if I inadvertantly mapped the bottom section of the wing in persp window it may have reversed its geometry?
