as you can surmise form the title, i'm W...E...A...K in ps. i have a rectangular capture that i want to round the corners of. like this:
i know a little about selecting. i'm killer with the magic wand! 
i think this should be easy, but i just can't get it. it's probably just 2 steps, right?
so, help me, please!
use the circle selection tool and position it so you get a rounded corner...then select inverse and delete it sohuld work
if i do that, it will delete everything except the circle, won't it?
You can always add to the selection to cover everything that you want and then select inverse...
Choose Rounded Rectangle tool > enter Radius of corners > Draw shape (it will be the area, that you want to be rounded) > Ctrl+click on layer with rounded shape > Ctrl+Shift+I (Inverse Selection) > make your main layer active and hit Delete.
thx wizard[wa]. that gets me real close. just some feathering/tolerancing/transparency stuff to fudge. and some manual touch up of the top left and right corners. man, i was close. so, what is the ctrl-click? i think that was my big roadblock. plus the fact that i was working on the background instead of a new layer. and should i do that on a new layer or a copy of the background?
i know, that's what the help file is for. but i always say: 'screw the joy of discovery. let someone else figure it out!' 
If you'll click on the layer (in the Layers window) with pushed down Ctrl key, you'll get the selection of this layer without transparent pixels.
PS You can change feather of selection: right click on selection area > Feather.
and should i do that on a new layer or a copy of the background?
When you're creating shape, it automaticly become a new layer. Click on this new layer with Ctrl and you will get selection of rounded area (mask of your rounded image) > after inversion of selection, switch on your source layer (which must not be background layer) and delete unneeded pixels from image.
You could always use a channel with a gaussian blur - then levelled into a perfect curve... I did offer do some tutorials on all this - but someone was heavily opposed to the idea......
so are you still planning on doing those tutorials? I think it might be interesting to many people here as lot of us are ****ie at photoshoping :P
Agreed tutorials would be nice

No, Wizard It WILL give you transparent pixels, it just doesn't highlight them. Example: If I blur a circle and CMD Click it it will show a selection of a small circle, but when I Alt/CMD Backspace to fill it, it will fill in transparent pixels. 
thx everybody (esp wizard[wa]). this makes me realize that i really gotta sit down with my ps book and do me some learnin'!
No, Wizard
You're right. I was talking about the pixels that are not exist (absolutely transparent), all pixels that are present in the layer (even if Opacity=0) will be selected (or highlighted, whatever).
