I have a document center with a custom master page. The page is designed with IE9/HTML5/CSS3 in mind. In my other question, I worked out how to fix the IM Presence icons by fixing some core SharePoint javascript that is defunct as of IE9. This time, I have noticed that when I click the context menus for items in a ListView web part or document library, the "Send To" submenu does not expand. This menu still works in Firefox, but people should just ideally be using IE for SharePoint for most of the functions to work properly. Has anyone else seen this, specifically? I know it must be related to the expandos issue in my other question but I have done a lot of digging and not been able to unearth the key location for the problem. It's like the javascript just stops running somewhere with little or no explanation.
Thanks,

. After this, I cleared the browser cache, reloaded the page, and beheld the issue. Hope this info will help other experts to participate in answering the question.
