Saving blank files
In the past, when I saved a file, a single file such as 1315.png was saved. In the last few months, every file saved includes two, one png, one with no extension. The thumbnail of the file without extension appears as a blank page. I was poking around my setup trying to solve another problem so I might have changed something inadvertently. Is there a setting I should change to stop the blank files from being created?
