I've been playing with Panoweaver, and once I have it down I'm going to purchase.  So far it's wonderful and soon I'll move onto Tourweaver and buy that.  People are waiting for me to get it down and the work will start. 

Anyhoo, my question is - I've stitched the pictures together, no blending or seam problems, but it needed a little photoshop tweaking.  I export it as a cubic image, cover up the tripod and did an overall image brightness/contrast ajustment.  When I reload the panoramic image into Panoweaver all of a sudden I have seams problems.  I'm cunfused since I did an entire picture ajustment, not just specific areas.  Is is because I exported cubic?  Where did I go wrong?

Any thoughts....

You should do all colour corrections and sharpening in spherical mode not cubic. Only mask out your tripod and zenith star in cubic mode without going near the edges and without any sharpening. then convert back to spherical.

Cheers smooth, that seemed to do the trick! 

One quick follow-up.  If you keep exporting and converting, will you eventually lose quality?

Only if you do your image using JPEG's

Otherwise keep the file type as a non compressable file type flavor

Yes, use a non lossy image format like .bmp, .tiff or .png. You can go back and forth without losing quality.
