A bit , i am hindered as i do not speak German so do not understand your
function/variable names but i've had a look.

woTermine_Scroll()  seems to fire all the time.
istFerientag() function runs a lot.

I have been testing by adding break points then holding down F8 key to see
what code is running.
in woTermine_Scroll() was a good place for a break point.

Also the application does not exit cleanly (I have to use the ide stop
button). either a file open or a timer not stopped is causing it not to
exit.

Sorry i cannot help further.
