Internet Explorer 9 issues with O365

Something really strange is going on with my Win7 / O365 / IE9 set up. Here's what I'm seeing:

1. My sign on screen for O365 tells me I'm using IE7 (see screen shot #1 below)
2. I am using IE9 (see #2)
3. When I attempt to download and then install a new IE9, it tells me I already have a later version installed???
4. Over the last few weeks, each start up of my IE9 requires several "refreshes" to get any site up. This varies a great deal, however, sometimes my remebered sites come right up, other times it takes 1-4 refreshes to get them up. Same issue on new sites.
5. I tried "Fix-it" without results

Any ideas on how to fix this?
