Seems I've put a dimension on the top copper layer

Question

Hi Forum, Really new to Eagle, and it seems I've somehow put a dimension (DRAW+DIMENSION) on the top (copper) layer. Now I can't remove it. I've tried ripup and delete but the copper (if that's what it is remains. Can anyone help? The forum package does not allow me to attach the files, so I have attached an image - the dimension was a 2mm spacing check - it is situated just under pins 1 and 2 of the 6 pin JST-PH connector "MOT_IO" - top right of the board. Any help would be greatly appreciated. Thanks, Chris

I'm afraid I cannot see what could cause this : ( What happens if you click the dashed box icon, and then drag to select a group, does it become brighter red than the stuff that wasn't selected? I've tried creating a dimension on my copy of EAGLE, but I can delete it using the usual delete icon (the one that looks like an 'X'). Selecting a group of parts does make it become bright red, which in my case means it should be deletable too. If in your case it becomes bright too, then that usually means it is deletable but that something else is being selected when you click near it. Also, If you select Info (the 'i' icon), does it display any information when you click on the dimension?
