CS4 and mac

Can anyone tell me if there is a way in CS4 with a mac to have the program show a solid background in the workspace?

I'm finding it REALLY annoying to try and work in Photoshop/Illustrator etc with other programs and windows showing in the non existent background working space of most of the CS4 programs...

I've tried searching for a solution but all the results are coming back relating to background pictures etc.

Do you get what I mean?
Here is a screen shot...

the circle is the ONLY thing open in photoshop while in the program
1. is a finder window showing through the PS program
2. is Eclipse (a program) showing through the PS program

HELP PLEASE!!

PS: advice along the lines of 'just make the image window full screen' not needed... want to see multiple files open in photoshop and NOTHING else in the background behind it

I don't believe its possible to do that on the mac. Its been that way back as as far as at least photoshop 6 on the mac. The funny thing is I actually like that feature and wish my vista machine didn't seem to need an application background.

Ahh OK. Am a new convert to mac so I have no idea if its normal or not, or an option I can just turn off

yeah it took a while but now i really like that feature

GB do you know how to delete something in CS4 photoshop without having to go up to Edit > Clear

?

It doesnt allow me to make it a shortcut and for some reason the delete button doesnt delete when I select something..
