Each time you start a program or open a document on your computer, a button is added to your computer's Windows taskbar. If you've got a lot of programs running or documents open, the taskbar can run out of room. When that happens, Windows will group similar buttons together on the taskbar, and it isn't always easy to re-find what you're looking for.
Here's how to change that Windows XP setting on your computer:
1. Right-click on any blank spot on your computer's taskbar
2. Click "Properties"
3. In the Taskbar and Start Menu Properties window, click the checked box next to"Group similar taskbar buttons" to remove the checkmark
4. Click the "Apply" button and you'll see the change
5. Click the "OK" button to finish
