Something I noticed here is that the CVS integration command "Show history" doesn't show the whole history in the popup window although I can see in the CVS console that all entries where received.
Has this something to do with the command "Make this project current" which doesn't seem to exist anymore but which I have used in one of the earlier builds. I never really understood the meaning of it and clicked it to make it show the difference indicator in the gutter, which also did not work.
Another thing I found out is that the difference indicators only show up for changes made in Aurora. Changed made earlier while using Ariadna aren't shown in this way.
