HTC Incredible :: Updated To 2.2 OTA / Sense UI Restarts

I received the 2.2 OTA update. The phone is not rooted. Ever since 2.2, the Sense UI restarts dozens of times a day. By "restart" I mean the while HTC screen, followed by (loading...) with a spinner for about 10 sec. It happens sometimes when unlocking the screen, sometimes when returning from some app (totally random, no pattern that I can see). I know, "Factory Reset" or "Wipe and do RUU" or whatever other old wives' tale you want to dredge up from the posts here. Those drastic measures seem to have created new problems for as many (or more) people than they've helped.

Meanwhile I've seen references to this issue woven within threads on the many battery life and browser lag threads, but no thread on this issue itself. At the risk of creating more old wives' tales ("Uncle Festus told me I should"), I'd like to see if folks can detect a pattern or an app that might be making it happen. I suspect it's a bug in Sense on 2.2 and not some app. It started immediately after my 2.2 OTA, and before I installed any new apps. It seems to happen more often after some type of notification like an alarm or something that puts a notification into the pull down list. Did it start right after 2.2? When do you see it? Has someone found a cure apart from "reformatting the hard drive" (the ultimate sledgehammer)?
