[Chameleon] session expired and popups

[bartvde@xs4all.nl]

Hi list,

we have noticed some strange behaviour (lots of error messages) in
Chameleon when a session has expired and popup windows are still open.

Is there a way to close all popups when a session expires to prevent this
behaviour, or can't anything be done about this and is it the
responsibility of the user?

Best regards,
Bart
