When I am editing images and I go to open a new file to work on it, at times it only shows a small portion of the files in the folder I am working in and if I click to open one of those that it is showing I get one of two things, either a blank screen or a copy of the last image I was working on if I hadn't saved and closed it yet. I have to close photoshop and re-open it constantly because it does this after every few files. It's getting to be very annoying. Attached is a screen shot. Please note that it shows a file is opened but there is nothing.
