IE9 on Vista keeps freezing when Outlook is running; other programs continue to run well (on Windows Vista) even when IE9 is frozen, and IE9 does not freeze up except when running Outlook or has a tab connected to Outlook.com.

Ctrl+Alt+Del starts up task manager ok, and End task closes IE9 properly, which then works well until Outlook is running, and contiues to behave with text based emails. It most often freezes when following an email link to a video clip to a youtbe or vimeo link; the link will play well, but Outlook and IE9 will freeze on trying to return to outlook, either by selecting the 'Back' button, or by closing the tab the link was on.

Any suggestions out there?
