Make sure the Wizard is turned on. Click the Tab Control tool. The default is 2 pages. You may add others by right-clicking one of the pages and Insert new tab. Pages are a nice way to get a lot of data on a small form.
Pages have several parts with separate properties.
Click the border where there is no tab to change fonts, color, etc of the tabs themselves. This is the area that contains other controls. Click the tab for its properties. Remember, the controls have properties. So you need to be aware of Detail properties, Tab properties, Page properties, and Control properties all at the same time.
