Old I know, but it has been sufficient thus far. Right now, it will not allow me to center my booklet document on my screen. Indesign is open to it's fullest capacity. when I scroll right to center the document to work on it, the minute I release the mouse button, it shifts back all the way to the left margin of the clipboard, so my booklet is 1/2 off the screen and not accessible to work on. Has anyone seen this before and know how to fix it?
