Blender Interface and Mac 10.5

This might actually belong in the "Builders" section, but I'm not actually at the point where I'm building anything.
I'm using Blender 2.49 on a MacBook Pro with OS 10.5 installed. I've had to use some of the work-arounds for things like the number pad and the three-button mouse, and they are not working quite as expected. Right-clicking on a toolbar, as the "noob to pro" tutorial says, should give me a menu that allows me to divide the windows on the screen. But the work-arounds that I've used, control-click and two-fingers-on-the-mousepad-click, give me a menu that allows me only to move the header to the top or bottom of a window, or remove the header completely. Control+number key should also orient my view to a particular point, but when I tried that, Blender replaced the cube that was in the field by default with a low-polygon sphere.
What's going on and how do I fix it?
