A dialog box appears asking if you want to browse the Active Desktop Gallery. Yes , and then browse through the different items available. To add an item to your desktop, click the Add to Active Desktop button on the item's page in the gallery. If you've used Microsoft Windows in the past, you might notice now that opening menus looks different than you're used to. You're not imagining it.
Menus now slide out from the menu bar.
When you right-click an item, a menu zooms out. And tooltips roll down when you pass your mouse over a toolbar button. Of course you can customize Windows 98 to turn these new effects on or off. Double-click the Display icon. Click the Effects tab.
