// 06.11.2003-12.11.2003
// you can use it without any limitations
//
// a lot of thanks to Peter-Paul Koch,
// http://www.xs4all.nl/~ppk/js/doctype_on.html
//
// ---------------------------------------------------
// additionally was modified by Paul Yanchenko
// (paul_y@mail.ru, ICQ: 122870822) 15/01/2004:
// * cleaning script (it seemes that original script
// was oriented to show images but was hurriedly
// modified to show text messages instead)
// * readable improvements (i hope that)
// * fixed 1 bug: when hint message shows it may cause
// window horizontal scroll and clipping hint message
// if it is near right corner of the browser window.
// Most often it takes a place at the first time
// after page (re)load.
// * width of hint message now is automatically assigned
// for proper wiew, but not more than 300 pixels.
// * added support for delay and timeout.
// * other cosmetical changes
//
// original script has been taken from
// http://www.ycc.ru/userfiles/map/enlarge.js
// ---------------------------------------------------
// usage:
// 1. include this script in of html-file:
//
// 2. place into of html-file:
//
// 3. each html-element with hint message should contain
// following attributes:
// onmouseover="showhint('Hello, world!', event, 500, 5000);"
// onmouseout="hidehint();"
//
// (you may use other events)
