In Photoshop CS4 (and in Illustrator CS51) I can zoom in on a section of the document by pressing Ctrl+Space and clicking-and-dragging my mouse to select the area that I want to enlarge. In Photoshop CS55, I do get the "magnify" cursor when I press Ctrl+Space, but when I click-and-drag the image is zoomed immediately rather than allowing me to select the area I want to enlarge. I've tried changing the four Zoom option on the General page, but none of them create the "zoom box" behavior. What am I missing?
With the Zoom Tool selected, uncheck the "Scrubby Zoom" setting up in the options area.
Perfect. Thanks Noel.
