I select a brush, I move the mouse on my image, I only see an X cross, I don't see a brush circle which normally should be.
How can I get back the brush circle that should appear when I move the mouse over my image
What operating system and version of photoshop elements are you using?
Can you post a screenshot of what your seeing including the layers panel and image?
Try turning off your Caps Lock.
Have you tried increasing the size of the brush?
Go to Edit>Preferences>Display & Cursors. What is checked in this dialog?
