Problem in stack window

Is there’s a way to avoid these “jpegs” in my stacks pop out window area? What I did wrong? I want to avoid it happens again. What’s wrong with Font File stack? Every time I load RW it upgrade the stack.



Scratch my earlier comment. You need to go into the Stacks preferences and uncheck the images options. See the screenshot in this link:

Thank’s Marten. It was as esay as mentioned.
