Mysterious outline of block when moving, trimming, ect.

[suicidedoors]

When I trim or move a block (roof trim mostly) there is an outline of the block I am working on, I know the solution, if you move the block over, it moves but the outline stays where the block used to be, then I copy it back and delete the outline or original block that made the outline and its back to normal. I am wondering if this happens to anyone else and if so is there a fix? It happens quite a bit on my workstation and is very annoying.

Attacments: Trim Bug01 is my trim

                    Trim BUg02 is my trim after its been trimmed with mysterious outline left over

                    Trim Bug03 is my trim after being moved with mysterious outline left in objects original place

Thanks for the help

Sometimes the AEC objects can display irregular behaviors similar to what you have outlined.  In these cases I recommend a cleanup be run on the file in question to rule out any AEC miscommunication or corruption versus an issue with the graphics system.  To do this clean up, please refer to the link below where this process is outlined.
