PS 7 does not allow alpha maps for TGA's anymore??

Hello artists,

I used to create my alpha maps in ps6, selecting the stuff then goin to channels, bla bla the usual way....
then i saved it as tga 32 bits and when i open edit 6.5 in my targa 3k it works like candy...
ok. i tried the very same procedure in my new ps7 and it doesnt work... its doesnt even save the alpha map anymore cos i tried to reopen the image later on and the channel wasnt there...
is there any problem between adobe and pinnacle???
Or even better.... Whats the matter with tga's alphas in PS7?????
thanks in advance,

They decided to "fix" the TGA file format as they thought it wasn't being implemented properly, so TGA's no longer support alpha channels but transparency only (on a layer). They did the same to PNG's in version 6.

Easy fix is to copy over the TGA import/export plugins from version 6 or below and just replace the newer versions.

Adobe fixed this problem. Just goto their photoshop support page. There is a replacement plugin.

Loggie, check it out bud>

The most significant fixes in the 7.0.1 release include the following:

• Photoshop now saves alpha transparency data in Targa files in the same way it did in previous versions.
• File Browser performance has been enhanced.
• If the color settings color management policy is set to "Off," Photoshop no longer asks to save changes unless other edits have been performed.
• The total ink now defaults to 300% as it did in previous versions of Photoshop.
• The color of white areas in CMYK files saved as JPEG files no longer shifts.
• TIFF files with LZW compression are now written correctly.
• Files made with Photoshop now work better with Microsoft® Windows® XP's automatic thumbnail generation.
• Favorites now function correctly in the Open dialog box.
• Picture Package no longer locks up when it encounters incorrect file types while using custom page layouts.
• Metadata is better preserved in certain JPEG files.
• Photoshop no longer appears frozen when applying KPT3 filters.
• Photoshop now offers better compatibility with older Intel® Pentium® III hardware.
• Photoshop no longer produces a program error when resampling certain large 16-bit documents.
• An issue that prevented Photoshop 6.0 from opening certain files containing layer effects and edited in Photoshop 7.0 has been fixed.
• The Maximize Backwards Compatibility for Photoshop Files preference now correctly sets the state of the Maximize Compatibility checkbox in the Photoshop Format Options dialog box when you save a file as Photoshop (PSD) format.
