Motorola Droid Razr HD :: Click The App Drawer And The Searching Circle Goes Around And Round And Then The Home Screen Will Close?

I was wanting to know if anyone had an issue with the home screen stopping. I have over 800 apps on my phone and wondered if maybe it was that with the app draw trying to refresh and it taking too long. When I did a search people were having this problem with only having 20 or less added apps to their phone. Some even had this problem after having their phone refreshed. I can run the phone for days and use it with no problem and nothing and then out of the blue there it goes. I click the app drawer and the searching circle goes around and round and then the home screen will close and go to the last app or web page I was on and it could be one from a few days ago. I erase all the previous history and when the home screen closes it just refreshes the home screen. The only thing I can do is reboot and wait about 10 or so minutes and its all good till the next time. The question I am wondering is what is causing this. I had someone comment on links or widgets on the homescreen might be causing it. I removed some and it does not happen as much
