You can be more specific about what is not working with the clone stamp tool?
What version of photoshop did you upgrade from?
Does the Clone tool use the GPU I wonder? Kromer, what setting do you have in Preferences > Performance regards GPU acceleration, and how many cache levels do you have set?
Your XP machine will very soon become a serious liability btw.
When I select the clone stamp, select an area to copy, and drag to copy
it, nothing happens. My previous version was CS2 so CS6 was a newly
purchased complete package.
Thanks for responding. I'm just starting to use CS6 so the preferences
are still at the default settings.
