Thanks for your answer.

Of course you were right about a programming error, I know that one
click gives two events, and I thought that I had considerd that, but I
confused the roles of event.press and event.type...now I corrected
that and it works now very well for the 'get one position'-function.
But I tried a function to get two positions, and this leads to the
same problem as before, I get my four values and then the crosshair
won't like to disappear. I guess this will be due to an similar
mistake in my code, although both functions have the same if-condition
at the beginning. But I hope I will find a nice little mistake.

Thanks again for your help,
Justus

I tried the clear_events keyword, but same problem. I recently found
out, that as long as I don't unset the draw_button_events, I get no
problem.
