Microsoft Office applications in particular were prone to these problems. There were always some nagging issues that would not allow Spaces to work correctly, due to the way Office windows are drawn on the screen. Over time, they started working better, but a few issues still remained with Office, especially in Word when the Toolbox floating window was in use.
With Snow Leopard's debut, however, Microsoft states that these issues have been fixed through "collaborative efforts" with Apple. Hopefully, this will help a lot of eager and frustrated Spaces users manage their many windows on their desktops.
Do you use Spaces, or have you held off because of these issues? Leave a comment below and share your experiences!
