Chrome CSS Menu - Firebug reporting error

[YellowSwordfish]

Chrome CSS Drop Down Menu (2.01)

http://dynamicdrive.com/dynamicindex1/chrome/index.htm

First off thanks for the great script. One day I'll understand how it all works when my js is up to speed! Now for the problem I am seeing which I can reproduce every time in two different places.

Step 1: Drop down one of my menus and make a selection.
Step 2: Leave the mouse pointer EXACTLY where it was below the menu bar.
Step 3: Wait for the page to fully load.
Step 4: Move the mouse pointer downwards and out of the area where the drop down would be if displayed.

Firebug reports the following:

cssdropdown.dropmenuobj has no properties
chrome.js (line 109)

which on my version is:

this.delayhide=setTimeout("cssdropdown.dropmenuobj.style.visibility='hidden'",this.disappeardelay) //hide menu

As I say my js is not good enough yet to understand the problem. Anyone know of any way to stop the error or the error being reported?

Thanks/Andy

Well, I don't have Firebug installed, but I assume the error would also pop up in Firefox's error console. Anyhow, please post a link to the page on your site that contains the problematic script so we can check it out.

Of course. Would have been the obvious thing to do...

This is a WordPress site. Try the 'About', 'Plugins' or 'Forum' menus. I'd select the top item and it does look like you need the page to finish loading.

Thanks for taking a look...

I get an "unable to connect' error when loading the site. I'll try again later.

Sorry to hear that. Unusual. It's Dreamhost....

Did you manage to get a look at this behaviour?
