IE 7 css menu glitch

Hi Experts,

I have a css menu that is working correctly in all browsers tested except IE7. The issue occurs when the cursor travels over the <a href> to make a hidden <div> appear. The div appears but as the cursor moves to highlight the next menu option the div disappears again.

I have been through my code again and again but can't seem to see what IE doesn't like.

Please see the example here:


Thank you for any advise to can offer.
width: 99%;
font-weight: bold;
.chromestyle:after{ /*Add margin between menu and rest of content in Firefox*/
content: "."; 
display: block; 
height: 0; 
clear: both; 
visibility: hidden;
.chromestyle ul{
border: 1px solid #BBB;
width: 100%;
background: url(chromebg.gif) center center repeat-x; /*THEME CHANGE HERE*/
padding: 4px 0;
margin: 0;
text-align: center; /*set value to "left", "center", or "right"*/

display: inline;
.chromestyle ul li a{

//** Chrome Drop Down Menu- Author: Dynamic Drive (http://www.dynamicdrive.com)
//** Updated: July 14th 06' to v2.0
	//1) Ability to "left", "center", or "right" align the menu items easily, just by modifying the CSS property "text-align".
	//2) Added an optional "swipe down" transitional effect for revealing the drop down menus.
	//3) Support for multiple Chrome menus on the same page.
//** Updated: Nov 14th 06' to v2.01- added iframe shim technique
//** Updated: July 23rd, 08 to v2.4
	//1) Main menu items now remain "selected" (CSS class "selected" applied) when user moves mouse into corresponding drop down menu. 
	//2) Adds ability to specify arbitrary HTML that gets added to the end of each menu item that carries a drop down menu (ie: a down arrow image).
	//3) All event handlers added to the menu are now unobstrusive, allowing you to define your own "onmouseover" or "onclick" events on the menu items.
	//4) Fixed elusive JS error in FF that sometimes occurs when mouse quickly moves between main menu items and drop down menus
//** Updated: Oct 29th, 08 to v2.5 (only .js file modified from v2.4)
	//1) Added ability to customize reveal animation speed (# of steps)
	//2) Menu now works in IE8 beta2 (a valid doctype at the top of the page is required)

You have a closing </div> tag before the submenu. The parent <div> needs to encompass both the top-level menu item and the sub-items. (You're also missing closing </li> tags on your menu items.)

I changed it as follows, and it works in IE7 on my local machine. Give this a try:

<DIV class=chromestyleOUT id=chromemenu>
  <FORM id=user-login-form style="FLOAT: left" action=./Login_Script.php
  method=post><INPUT id=Username
  onfocus="if(this.value=='Username') this.value=''" size=12 value=Username
  name=Username> <INPUT id=Password
  onfocus="if(this.value=='aaaaaaaa') this.value=''" type=password size=12
  value=aaaaaaaa name=Password> <INPUT class=bodyTxtSmallWhite
  style="MARGIN: 0px 30.5em 0px 0px" onclick=./Login_Script.php type=image
  value=Login name=Submit> </FORM>

Hi slovisa, Thanks for taking a look at this. I have cut 'n' pasted the code you posted but it's still disappearing when I come off the btn on my IE.
My version is: IE 7 7.0.5730.13

The code that you sent is up there now. Is it working for you?
RowdyBurnsAuthor Commented:
Slovisa, Please don't spend anymore of your time on this. We are going to drop this menu as it's just not working well. We have spent a long time trying to get it working in all main browsers and it just isn't woth the time. We will run with a standard set of links.

Thank you for your help.
