This problem has been resolved for me. As you can see in earlier posts, I tried reinstalling MM to fix this problem. Unfortunately that didn't work. However, I recently had to do a fresh install of my entire operating system because of hard drive failures. Anyways, after reinstalling my OS and MM, I restored MM from a backup. Then I opened MM and I noticed that the spinning aero peek bug was gone. It now works as it should. I'm not sure if it was the OS reinstall or the newest version of MM that fixed the problem. Or perhaps it was a combination of both? Either way, I am pleased to finally have aero peek working for me.
