Yes, there is a setting in Excel that controls the behavior of the mouse scroll wheel. Here's how you can enable it:

1. Open Excel and click on the "File" tab in the top left corner.
2. Click on "Options" at the bottom of the left-hand menu.
3. In the Excel Options window, click on "Advanced" in the left-hand menu.
4. Scroll down to the "Editing options" section.
5. Check the box next to "Zoom on roll with Intellimouse".
6. Click "OK" to save your changes.

Now your mouse scroll wheel should work in Excel just like it does in other Office 2007 products. If you have a different type of mouse, you may need to look for a similar setting in your mouse software or control panel.
