I am now running V2.35.1223 also, but I run Windows 7 and Firefox.
I no longer see any cookies left in my list even if I visit msnbc.msn.com. I notice that CCleaner is now deleting all of my LSO (Flash cookies) as well as the normal browser cookies.
In short my observations of 2.35.1223 are not the same as yours. Our different environments probably explain that but at least all ends well after a reboot. Perhaps some XP users will weigh in.
