Photoshop: Merging exposures into an HDR image issues (Lion OS)

When trying to merge three different exposures of a subject (three dng files), my single (merged) image is very dark and strange. The result does not seem correct considering the files used. I attached a screen shot of the result.

Other people running a previous version of the operating system do not appear to have this problem.

Any feedback would be greatly appreciated.

Looks like there's something wrong with the exposure metadata (note how the EV is the same for the first two images).

It doesn't look like a proper bracket to compute an HDR image.

See how a proper bracket looks:

Almost looks like you tried to fake 3 exposures from a single camera RAW file -- which doesn't work, and doesn't give any advantages because all the data in the RAW file fits in 16 bits anyway.

I'm following a book's example as I'm learning to use the merge tool and the three images I'm using are provided on the book's CD. The steps to do this are pretty simple but I can't duplicate their "normal-looking" merged image. If you like, I could provide you with the three images to see if you can duplicate my problem...

I'm wondering if there is a setting somewhere I need to reset... or if it's the Lion OS not cooperating with the latest Photoshop version.
