I run Photoshop CS6 on a windows 7 machine. It has started having two problems:
First, when trying to crop, as soon as I release the mouse button after blocking the frame to crop, the screen goes black - No controls, no picture, nothing. I have to close Photoshop and restart to get back to the photo.
Second, when using clone stamp, as I click to clone the photo switches to odd colors (almost like it was polarized). The color returns to normal when I release the mouse button.
What is going on and what do I do?
Update your video card driver from the GPU maker's website, or disable GPU drawing in Photoshop if you cannot update the driver for some reason.
