Navigation

When navigating between pages, the hourglass will be shown and hidden automatically and will override the current visibility settings. The position the hourglass is shown at during page loads will be as set using the Left / Top properties. Because the Hourglass is shown and hidden automatically during page loads it is not recommended to use static meta tags to show or hide it, in preference use InvokeMetaTag from JavaScript.
Scrolling

The hourglass is not compatible with scrolling the browser window. The spinning cursor will move with the HTML page.

Supported Platforms Windows CE, Windows Mobile

Persistence The hourglass position persists across page-loads, and is hidden once the new page is loaded.

Min. Requirements None
