Do you mean PSE 7 or Photoshop 7 (very old version of full Photoshop)? If the latter, you might get better answers in the Photoshop forum:
After I edit the picture in Photoshop Elements 7,
I click on "File,"
And then "Save As."
However, approximately 30% of the time, the "save" or the "save as"
buttons are not available; they are "grayed out."
I then have to close the program, reopen it and start over.
Thanks for your help,
