shortcutted at my office to be LAC.
we cant use the layer palette, it makes switching between drawings way too slow. Been complaining to autodesk for some time about it, they still havent fixed it.
I use -layer (defined as LA in my pgp file) for most everything and classiclayer for those random occasions when I need to do something I can't from -layer.
I solved the problem here, by setting layerdlgmode to 0 in our acaddoc.lsp
