Indeed, and thanks!, although it's pretty FRIKKIN annoying that the IMAGE/CALCULATIONS command is ghosted if two alpha channels are selected. (grrrrrrr)

WUWT, Adobe???

I often prefer to do it myself - i.e., Ctrl-click (or Command-click on a Mac) on an alpha channel to select its contents - then go into another channel and either fill that selection with white or black as needed. Hope that makes sense...
