do not work on your Google Mail address book in parallel!

I worked on my address book in two different tabs of my browser. That was actually Google Chrome 8, but I think, that doesn't matter. If you modify and save an address book entry in tab "B", you will not see these changes in tab "A". They are not coordinated, and that's not optimal. I am quite sure, the changes in tab "B" are still updated on your persistent database at Google's sites, and you can expect to see the changes, when you load your address book anew.
