IE 9 pulldown menus not working in latest 4.4.3 Jira

I'm a Firefox fan but several of our developers and most of the management are using Microsoft's Internet Explorer 9. There are several cases where the pulldown menues are not working:

1/ On the IssueNavigator page, the 'Views' or 'Tools' pulldown menu do not work.
http://jira:8080/secure/IssueNavigator.jspa?reset=true&jqlQuery=assignee+%3D+currentUser%28%29+AND+resolution+%3D+unresolved+ORDER+BY+priority+DESC%2C+created+ASC

2/ As well, on the IssueNavigator page, the individual 'Actions' pulldown menues do not work

3/ Under the top level 'Edit' menu. i.e.
http://jira:8080/secure/EditIssue!default.jspa?id=15479
None of the pulldown menus for Component/s, Affects Version/s, Fix Version/ but the pulldown menu for Assignees work.

In summary, IE9 is a support platform in Jira 4.4.3 but it definitely does not work on Windows 7. It does work on latest Firefox, Safari, Chrome and IE8(on Windows 7 or XP)

I don't want to be telling my management team to use another browser especially when IE9 is suppose to be a supported browser.
