This is a core JavaScript function for writing cross-platform dynamic HTML. It takes the ID of a positioned HTML element and returns an object reference. This version is the light version - meaning that it's small, but also that it won't work with nested DIVs in Netscape, or with global styles in Internet Explorer. So if you use this small function, you'll need to restrict yourself to non-nested inline styles.

Usage: foo = WM_checkIn('id');

Cut, paste, and enjoy!
