Well, what can I say...
Trim was the one I was looking for. It sat there all the time, just in front of my nose.

Thanx.

Is there a script that allows one using the subtract tool without deleting the first part?
As it is now, I have to make a copy of the 1st solid, place it in a nearby spot, do the subtraction and then place the copy back to the original place...

Thanks flipya, worked great!

When I try to launch the preferences, the preferences window does not show up.

It seems it's hidden behind something, I've tried to move things around but it is nowhere to find. The SketchUp main window is freezed and the one and only way to come back to SketchUp is to hit the enter key (wich I guess means I hit the OK-button in the invicible window).
I got loads of plugins installed. I use SketchUp 7.1.6860 Pro, on a 32-bit Vista machine.

Anybody knows a solution?

I need some feedback, some PlugIns seems not to be loading to the context menu. As an example, the PutOnLayer.rb doesn't show up. When I bring up the context menu I can see a couple of horizontal bars at the bottom but no menu item between them.
I've attached this image of how it looks like right clicking on a component with subcomponents in it...
