Re: AutoCAD 2010 layer issue
Hi, welcome to AUGI.
Perhaps you have a layer filter that is applied to the toolbar. Pick the layer manager button that shows a spanner.
Re: AutoCAD 2010 layer issue
When this has happened to me, it's because the current layer list is a subset. Open the Layer Manager and you see a list of layers. The window on the left will tell you if you are looking at a filter or xref or some other subset (if it's not there, open the Layer Filters pane). Select All Layers. You should see the entire list, and that will carry over to the pull-down list.
