New Group Filter (Layer Manager)

[B-Grif]

Anyone know why my AutoCad 2009 will not let me select new layers to a specific group layer filter. It was working just fine and yesterday all of sudden it will not let me add new layers to a specific filter. Is there a button or command that maybe would have changed that function. Everything else seems to be working on the Layer Manager. Thanks for your help.

What type of error message, if any, are you seeing?

After I select the layer I want to add to the filter, nothing happens, no layer added, but when I try to click on anything it gives this error message "unable to modify layers while another command is Active". I can close the Layer Properties Manager and then the error message goes away. Is there anything in the "Layers States Manager" that I could have mistakenly click on that would cause this?

Are you drag/dropping the layer into the new filter group? I see nothing in the layer states manager that would genereate an error message like that. I tried to replicate the problem but could not get the program to act the way you describe.. Im at a loss here...
