If you´re opening one of your PIM applications ( Mail, Calendar or Contacts ) with your Lotus Notes Standard Client, it looks very
different to the Lotus Notes Basic Client.
For administrators or people, who are supporting persons with the Lotus Notes Basic Client, but having installed the Standard Client,
there's a possibility to display the PIM application in the "Basic Look and Feel":
On Windows: STRG + ALT + Click on the PIM application
On Mac: ALT + CMD + Click on the PIM application
