Not sure if this is directly related to Chrome, but when the screen refreshes, my message treeview collapses and the number of messages is very large. Like 1620 under Foxpro, 1926 under Chatter, etc. Doesn't matter if I use the "Go back" function, as soon as the screen refreshes, it goes back to the collapsed view with tons of messages. Hilmar? Is yours doing that?
