I have 2 sites, one is mainly just for testing, unfortunately its the live site that has the problem .. grrr.

Ok in the forums on the respective sites there are menus that appear when you run the mouse over them, these menu's are ONLY in the forums.

Under Firefox/Opera/Mozilla/Epiphany (what ever its called) these menu's work fine.

In IE the menus do not pop up.

I have IE 6, on winXP with Service Pack 2. (each of the users that have mentioned the problem are in the same boat here - so one test I have not had the opportunity to try is does this effect SP1 users or users of earlier IE versions?)

I think the problem relates to the way that IE deals with .png images, BUT I am not sure, as the exact same forum is used at my test site and the menu's work fine at this site.

The site admin at the failing site emailed me to let me know that the menu's do work if you use an anonymizer style service. Which is even more confusing.
Service:
http://www.the-cloak.com/login.html

I don't mind chopping and changing code, but I don't know what to change as the problem only seems to effect IE users visting one site.

One more point is that IE users make up just under 50% of traffic, its enough for me to want to figure it out, but not enough for me to rip everything out and start again.

I wonder if another pair of eyes might figure this out.

A link to my test site (a working -test- forum):
http://www.dickinsd.f2s.com/modules/...c_id=1&forum=1

And a link to a thread on the site that has the problem:
http://www.linuxjourney.com/modules/...id=145&forum=4

To test:
Open the link, hover your mouse above the name of each poster, on the working site a menu will pop up which offers you a link to the users profile.

Any suggestions:

Thanks
