I am new to Photoshop (CC). I have been using some tools successfully, but now when I try to use the Healing, Tool, Patch, Type and some others, the image drops off the screen as soon as I place the tool onto the screen. Then I cannot work on the image. It just started today. Amy ideas???
Usually any issue thats have to do with the displaying an image or any part of photoshop for that matter, is due to an out dated video driver. Try updating it and see if that fixes the issue.
If the image is just too large to display, you can hold the ctrl key and the 0 on the numeric panel to zoom out to the full size of that image.
Are you using Windows 8? And does the image window go transparent, or to a solid color?
If so, updating your video card driver from the GPU maker usually works around it.
