Stuck again - Strange grey duplicate that i can't delete or select

Hi Guys,

I have been plodding along quite well, using the forum to answer most of my questions without needing to post, so thanks again for that, anyhow I am now stuck;

I have been working on a 3D subsea frame and somehow I have done something to my drawing, basically when I select the frame I get a grey copy (only of the lines not the solids) in the distance in my CAD window, if I have not selected the 3D "solid" frame I can not see them but even when I have selected the frame I can't do anything with them, as soon as i try to click them I dis-select the frame and they disappear, sorry for the poor description, some screen grabs should be attached to this (note: green is the frame, grey is the problem).

Thanks for any help

I believe this problem was discussed in a previous thread but at the moment I am at a loss to find it. Please attach a copy of the drawing that is exhibiting this strange behavior to your next post. Someone here will have a look at it and most likely explain what the likely cause of the problem is and/or how to solve it.

liquid: It's day three. Did you manage to determine what was happening with your drawing?
