I have used photoshop 7.0 for a while and on occasion, the clone tool and the lighten/darken tool gets where it is just like a "pen" instead of the "circle" that I'm used to. No matter how high I set it. What causes this and how do I fix it. I'm obviously "fixing" it but don't know how it's happening. It's very frustrating when I'm working on something and I need this tool a lot especially to alter photographs of my customers. Please help. My email is: [email removed]
