Hallo p-p, I'm experiencing something similar. My Sprymenubarhorizontal runs
perfectly in Firefox, but is dead slow in IE 7. The top menu items load, but on
mouse-over the IE tabs shows that it is processing info (a little IE 'rotating'
circle appears in the tab ear), it then produces the next level of the menu -
but only after a few seconds, which feels like an eternity. And so it continues
as you go deeper into the menu.
I've validated my pages menu content file (I've put a server side include into
my pages with the content in a separate file). But that didn't sort out the
problem.
I've now update my Spry from 1.4 to 1.6.1, as I've read somewhere that this my
help (although there was no feedback on whether it solved the problem...).
Update was downloaded at
http://labs.adobe.com/technologies/spry/. Once
downloaded you have to run the 'updater' file in the dowloaded folders (...spry
1.6.1 24oct08\spry_p1-6-1_022508\Spry_1_6_1_022408\dreamweaver) to install an
extension to Dreamweaver - which enables the new version of Spry. As far as I
can tell the Spry script and css updates are then available, but not
automatically applied to your existing sites. It's probably a good idea to
backup your existing site files before messing around with the new spry...
I haven't tried using the updated version myself yet and won't be able to do
so before tomorrow at the earliest.
I'm frustrated by how little info is out there on this issue. Googling brought
up your post, an unanswered post in some or other forum and a question posed on
"Exchange Experts" (something like that) - where you have to subscribe and pay
a monthly fee and hope their answer solves your question... I'm not willing to
go that route.
I'll let you know if I get any solution and will be watching this thread with
hope in my heart :-). 'till later!
