When I use the copy tool, not copy and paste, the object that I copy doesn't show up. I click on an object click the copy took then click in the location where I want the new object, nothing shows up. Then if I save the drawing, close and reopen it, the object will be show up in the new location. This is getting frustrating. It sometimes happens with move and rotate. I'm using 2013 64 bit version on Windows 7.
>> the object that I copy
What type of object is it? Does that happen with every (also new) drawing(s) with just a line as object?
Do you have some objects in front and maybe the copied one is in the background of drawing-order after defining the new position?
One try is to disable to hardware-acceleration to be more safe for some incompatibilities of your display driver (command _3DCONFIG ==> manual tune)
