Multiple Windows

Currently if a user does the following:

  1. opens a window and logs into our app
  2. opens another window pastes the url to our
  3. clicks around this 2nd window
  4. returns to the 1st window
  5. clicks - we get communication error

Is this typical of Vaadin? If not where should I start to look?

If it is typical, any advice on dealing with this, A big nasty red communication error screen does not instill confidence to our users.
