I've attached the drawer file although you'll need to reassemble it.

I know you're working on a big project and it must be something you have interest in but it would be wise to start with a smaller and simpler model so you can get the hang of it.

As I mentioned before, scaling is usually not the appropriate way to resize things when there are details that need to remain the same. The Move tool is a better choice most of the time. You can see some of that here. When Scaling can be used successfully, you'll generally want to open base level components and scale the geometry.

The Cutlist plugin is available in the Extension Warehouse. Get it there and let SketchUp install it automatically.

I'll PM you with some suggestions.

Have you tried to see if the mouse is supported...?
I can only think of a visit to the manufacture website to see if they have a compatible driver/software...?

AH YES!!!!! Thank you, this had me going in circles......

Are you using the default blue-gray background color? I find that the green protractors and lines are particularly difficult to see against it. I have my background set to white and that works for me.

There's a plugin that will create a cut list and export a file that can be read in CutList Plus which does the optimization. Look here.
