In the home screen of my Galaxy Tab I accidentally deleted the widget which showed me the active applications running in the background. Can anyone tell me how I can restore this?
Sounds to me like you deleted a widget. Long-press on a home screen, choose Widgets from the popup menu, and see if there's one matching your description.
Try pressing and holding the HOME button (hardware button in the bottom row) - that should pop up a screen listing recently opened apps. I believe the Galaxy Tab's interface has been modified to include a TASK MANAGER button. Is that what you're looking for?
I think you are talking about the program monitor widget: long press anywhere on your home screen, choose
Widgets and select the
Program Monitor from the list.
