Installed CS5 design premium on a new dell precision with 12gb ram running windows 7 in 64 bit mode with a wacom tablet. In InDesign i can point to an icon on the control panel or any panel on the right, and i'll see the tooltip, but i cannot click any button. I have problems selecting tools with the mouse but the keyboard shortcuts work. For example, pages panel, double click a page, nothing happens. Click the new page icon, nothing happens. The menus and panel menus work though. I deleted the prefs file, no change; Stranger, i opened illustrator and all the panels and buttons work just fine. I've also tried disconnecting the wacom and using an external mouse, and the problem persists.
