I have a simple block in my tool pallet that i put in my shop drawings to show floor depressions. It is attaching itself to items. I figured out the name of the block (which is '-2') is what is causing the block to attach itself. Not sure why it does this. It doesn't matter if I am in a live drawing or a shop drawing with overlaid xrefs. I changed the name of the block and the issue went away. Does anyone know why the name of the block would cause it to do this?
