saving tagra files with alpha channels in photoshop 7

when I try to save a tagra file with a alpha channel in photoshop 7
the box for the alpha channel is greyed out, with an warning sign next to it, and
the line below stating "file must be saved as a copy with this selection"
When I examine the saved file the alpha channel is not there!

Has anybody got any idea why?
My old version of photoshop 6, allows you to save alpha channels!

Not meant to be a daft question, but did you do as suggested and save as a copy?

PS 7 no longer opens the fourth channel in a Targa file as an alpha channel. It loads the fourth channel as transparency, which is the correct method according to the targa file specification. The data in the fourth channel is unchanged, and still available, but appears in a different place and is used slightly differently.

Also in PS 7, alpha channels are not saved with Targa - transparency is saved instead.

If your workflow requires you to use an arbitrary alpha channel instead of transparency, you can download an alpha channel version of the targa plug-in from here:

It is located in the Photoshop folder>Plug Ins>File Format>Targa.
