[support] one session in multiple browser tabs/windows (drupal 5.7/6.2)

[Matej Svetlík]

hello,

We are using drupal for our intranet. Users need to work with multiple
modules at once, so they open e.g. SMS module in one window and EMAIL
module in another ... sometimes they experience "Validation error,
please try again.  If this error persists, please contact the site
administrator." errors. 

Can one user work with multiple windows/tabs?

thanks
