Welcome to Seven Forums APrince. I suspect the issue is caused by the different resolutions of the 2 screens. Does the primary desktop display revert to normal when the desktop isn't extended? (I am assuming it does). I'd suggest if you want to keep the original layout while in extended mode, that you try the Free Fences
, and see if it can maintain the layout while extended. Or try IconRestorer
which enables you to save up to two layouts for each resolution.
