It is easy to open multiple windows in QuickBooks. When working on a project, it is easy to have 2-5 windows open. It is a pain to go back and forth, trying to find all you open windows, so you redo your report and now you have more open windows.

STOP THE INSANITY.  Simply choose to open the "view open windows" option under the "View" command.  That will open a small window on the left-hand side of the screen.  It acts as a small window manager. allowing you to toggle between open screens.  Give it a try, it will make QuickBooks a little easier to manage.
