Hi, thank you. Yes the borders ’disappear’ when I select another layer but to move/nudge the layer I have to select it again. And here’s that pesky border again!
Oh my – I made it, thank you so much for your help! I went to ‘Files > Relink Files’ and tried to select the correct file, alas FCP crashed. Opening it again. though it did relink and all is good again 😉
