Anyone else experiencing this bug in CS4 - when starting a new selection (Marquee Tool), random sized boxes will appear BEFORE dragging and releasing the mouse button to define a selection. The boxes will often extend from the first mouse click to an image edge, but it's unpredictable. I need to release the mouse button, deselect (left click), and then start over again. Once this behavior begins, it can recur repeatedly, making marquee selections VERY frustrating.
It also occurs with the zoom tool.
I´m running Photoshop CS4 on a brand new Dell Latitude (integrated Intel graphics) on Windows 7. The CS4 is also a brand new installation. I´ve tried a couple of different mice and also disabling Open GL. I had the same issue on other laptops I used over the years but not on all of them.
