Hi, I have a puzzle that is difficult to fix,
My website running drupal on wamp is running fine with Firefox and safari. But IE performance is bad. The symptom, IE performs the first couple of gets, then delays 5 seconds and then the next couple. The total page takes nearly a minute. But in firefox its only 10 -20 seconds.

I suspect something in the generated code, however I have it on every page of the site.

This is from the performance:

+ 4.565		0.007	641	852	GET	200	image/gif	http://www.mondialagency.dk/sites/all/modules/deluxe_menus/top_menu/deluxe-tree.files/xptitle2_black.gif
+ 10.738		0.005	0	0	GET	(Cache)	text/html	http://www.mondialagency.eu/userfiles/craftysyntax/livehelp_js.php?eo=1&department=1&serversession=1&pingtimes=15

note the jump from 4.565 to 10.738 seconds, what is happening there?

I hope you can help me figure out what to change to make IE perform like Firefox.
kind regards from Groningen
