PS 7 Mask layer question?

[scolds]

Hi, I get different results on 2 computers. Both loaded with the same CD. I create a new document black background. Paste a picture in to it. Go to Layer, Add layer mask, reveal all. Then when I go (PC based) to use the Gradiant Tool set up as Normal, 100% and I use it, then it works but when I then go to use it again the first bit of grading is reversed and the part of the picture reappears (On the other PC this doesn't happen). So therefore I can't use it as I wish to aid the merging of 2 or more photos together, I end up using the Eraser tool. It seems that there must be some option selected that I can't find and it is driving me mad, If anyone knows the answer it would be a great help. I am on XP.

Check out the gradient you're using. Is it white fading to black? Or is it transparent fading to black?

Try using transparent fading to black.

Thank you for the reply
I don't have transparent fading to black? My choices are Fore to background, foreground to transparent and White to Black are the first 3 options.
Is there a simple way for me to use the gradient tool to aid the mergeing of 2 photos? Maybe I am making this hard?
