If you have the Express Tools loaded in 2004 just type LAYFRZ on the command line and pick the layers you want frozen.

If you want to become productive with AutoCAD, learn all the typed commands. Especially the most often used commands.

Each time you click a button, look at the command line and the typed command will show up just above the command line.

Also open up your pgp file all the commands (short cut keys) for the most common commands are listed on the left.

Once you start using the keyed commands you will gradually start adding more to your bag of tricks and someday like me you won't have any icon commands anywhere on your screen, which gives you more drawing area on the screen.
