+| 2001-11-25 | Added a resize to the tooltip if the document width is too     |
+|            | small.                                                         |
+| 2002-05-19 | IE50 did not recognise the JS keyword undefined so the test    |
+|            | for scroll support was updated to be IE50 friendly.            |
+| 2002-07-06 | Added flag to hide selects for IE                              |
+| 2002-10-04 | (1.1) Restructured and made code more IE garbage collector     |
+|            | friendly. This solved the most nasty memory leaks. Also added  |
+|            | support for hiding the tooltip if ESC is pressed.              |
+| 2002-10-18 | Fixed verrical position in case of scrolled document.          |
+| 2002-12-02 | Mozilla bug workaround related to mousedown and move.          |
