// The following code is used to support the small popups that
// give the full description of an event when the user move the
// mouse over it.

// Developer's note:
// I (Benoit Maisonny <benoit@synclude.com>) tested this code with Mozilla 0.8.1 (on Linux),
// with IE5.5 SP1 (on WinNT4) and with Netscape Communicator 4.74 (on Linux).
// Netscape 6.0 and 6.01 seem to have a bug related to the visibility attribute.
// I suppose it will be corrected as soon as they release a new version, based on
// a more recent Mozilla source code.
// I'm not able to test this javascript code with IE4. It'd be glad to know if it works.

//	evt is a pointer to the Event object passed when the event occurs
//	name is the ID attribute of the element to show
