are their windows maximized or do you minimize them when you first launch a new app?
That would cause the app not to appear on the desktop but still display that apps menu bar.
Try the same thing without minimizing any of the apps.
If this is your normal practice, you may want to take a look at Spaces.
When I have many applications open (ie Lightroom 3, Firefox, iCal, AdressBook, Apple Mail, etc.) and try to use CMD+Tab to go from one open application to another, the top menu changes to that application but below window/screen don't always open for that application. Is there something can do to correct this problem? ADubin
