(The submenus are visible all the time, the subsubmenus are thosethat drop down.)

The intended behaviour of the subsubmenus is that they appear onhover and disappear again as soon as the cursor leaves. This happens on browsers that use HTML as defined by the internationally agreed standards (W3C).

Microsoft has chosen to deliberately ignore the standards (see dedicated page), so Internet Explorer gives slightly different behaviour.

We have tried to fix this several times with different javascripttweaks, but without full success.

If you find a fix for this that does not violate the HTML standards, then please email me with it!

However, they do disappear when the cursor hovers over anothersubsubmenu item. This is the best solution we have found for Internet Explorer while staying with the standards. If the subsubmenu list is in your way, hover over another submenu item that has a shorter subsubmenu list.

If you use Internet Explorer AND have ActiveX enabled, then the subsubmenus never disappear. This can be solved by your disabling ActiveX on your machine.

If you get the popup window saying that some ActiveX content hasbeen blocked, don't allow it but leave it blocked.
