$\text{Notes and tips about SWF applets:}$ 

• Our previous SWF applications were programmed for Adobe Flash. 

• Since the Flashplayer browser plugin is no longer supported for security reasons, these applets must be opened with the  »projector version«. 

• You don't need to install this program and it is not integrated into your browser. There are no security gaps in this respect  $($as long as you trust the  »LNTwww«$)$.

• On the WIKI pages for the above SWF applets you will find the projector version of the flash player and of course the applet itself. 

• Unfortunately, these applets  do not work on smartphones and tablets.

• All SWF applets  use the German language.
