Hello, Michelle, Thank you for using Workbook Manager and for the question. The question is not silly at all! If I have understood you correctly, the following steps will help: 1. Maximize your Excel file to make it full screen. Run Workbook Manager. Left-click the name of the tool in the upper left corner of the tool’s window and, holding the left click, drag the window to the left side of your Excel book. When your mouse reaches the left side of the monitor, a green stripe will appear.

As soon as you see it, release the mouse button. Please let me know if this helped!
