Invert a layer mask? Can't Ctrl + I

you'll get used to it. (their stockholders are betting on it!)

Ah, CS3 Extended. I was going to purchase that as an upgrade, having had every other version as a stand-alone since 2.5 (except 5.5), BUT, I had used my S/N from AI to get the upgrade to Adobe Production Studio Premium CS2 for video. It included PS CS2, which I really didn't need, as I had it on my two machines already. Went to upgrade to just PS CS3 Extended, but could not, as I NOW had to get the full-boat boogie package for Premiere, et al. Bummer. I do not want anything else in CS3, except Extended. First time I've ever been miffed at an Adobe upgrade policy. I had cut myself off from ever upgrading one component, even if I had previously owned it/them as a stand-alone. Will wait for CS4 and just take out a second mortgage - if I can get one then...

Ha! So exactly right.

there. fixed that for ya. :)

Your file is a PSD 32 bits
i per
channel? (ie, not a 32bit total file)

also looks like 32 bpc layers and masking is a CS3 Extended only feature:

John Nack on "What's unique to Photoshop Extended?":
>Support for painting and layers in 32-bit/HDR files. Merge to HDR is enhanced in both editions, as is basic HDR editing (e.g. using Levels). The rationale for dividing the HDR enhancements is that the photography-centric parts appear in both editions, whereas the aspects geared towards film, 3D, and technical work are in Extended only.

I had to delete my preferences :S
Feels like I have to do it on a near weekly basis now to overcome weird behaviours

>Looks like there are no layers, let alone layer masks, for 32 bpc images.

There are here. CS3 Ext.
I can make layer and mask in 32 bpc...
just don't see how phillr solved the issue.

Well, I still don't see it working in 32 bpc, on the mask or layer.
I'm glad the OP's problem is solved, but I'd like to know how he got there.

>Oh goodness. Deleting the preferences worked! Thanks for saving me hours of future grief!

It did?
I cannot Invert in 32 bpc Mode either. The Invert command is grayed-out in Image>Adjustments menu.

All works as expected when I convert to 16 bpc.

Hm...
