In the program you are using to view the image are there any little buttons with icons of magnifying glasses on them? If so, you might be able to alter how you are viewing the image. I'm guessing that now you might be able to see either the taskbar or the title bar - if you can tell us which program it is you are using we can maybe come up with more precise instructions!Well I think I've sorted it temporarily for now - by opting to open the files etc in imaging preview it comes up as a normal image with options at the top. In imaging it is still huge so will just leave it for now.
Best wishes
