My wife is having some issues with her new MacBook and MS Word... While having multiple windows open she uses expose to switch between them. About 1/3 of the time she clicks on a window, it appears for 1/2 a second, then her original window appears. This makes it very difficult for her to navigate the windows she has open. There have also been a few times where one word window appears over her current window. Has anyone else experienced anything like this? Thanks!
