Our SharePoint 2007 site is having problems displaying the dropdown menu options. What I've found so far...
One Site's Suggestion:
Not sure if i've been having a problem with the same type of menu's but under
'Tools>Manage add-ons>Toolbars and Extensions' I had something called
"NameCtrl Class" set to ENABLED. Once i disabled this my menu's started working
again.
Prior to finding this i had played around with all my security settings
(which had since been reset back to default) and played around with a bunch of
other feature's in IE9 (again set back to the way they were). But if i flip the
above back to ENABLED my menu's stop working again.
The extension is listed under "Microsoft Corporation" in the list, so I think
it came from a windows update, but I haven't researched it so I don't know what
it is or what it does.
Hope this helps.
Edit:
Before anyone mentions how it's silly to just disable something without
knowing what it does.
NameCtrl class is an ActiveX control that will "Display presence information
for people, integrating with Outlook (mail, calendar) and Communicator (instant
messaging)". Now that i know this, I'm wondering if there is a correlation
between this and MS Office 2010 having been installed around the time i noticed
my menu's stop working.
Another Site:
Could you please fix IE 9.0! When I use IE 9.0 (x32) on WIndows 7 to view SharePoint (Enterprise Edition) pages (any page), I see that the IE 9 memory process grows by about 6 MB everytime I refresh the page or navigate to a new page. Since I work with clients that spend a lot of time on the SharePoint pages that I build for them, it means that local machine memory consumption goes up rapidly (100 clicks --> .6GB !) and they believe that SharePoint is slow and causes the browser to crash frequently.
I have done quite a bit of research on this issues and have concluded that the culprit is IE 9.0 (x32), most likely the add-in "NameCtrl Class."
