If you have opened the standards view and switch to another tab without closing the view or the entire page first, then the time continues to run.
For this reason, we recommend that you always close the view correctly or pause it by clicking on the pause button.

If you close the Beuth WebShop completely (intentionally or due to a system failure), the expiry of the time quota will also be stopped.
