Double Click settings

When I go into CUI & try to customize the double click for say line & set it to bring up the properties box it works, but it changes all double click actions to do that unless there is already a default double click for a particular command. When I  set the double click in the hatch command to edit the hatch (hatch box pops up) it works but it will change the line double click to do the same thing. I don't remember having this problem in 2009. I'm saving in the CUI every time I try this.

I must be doing something wrong. Any help would be great.

Thanks,

Ashby
