Thanks, that's indeed the case!

In the cylinder-cylinder collision the cylinders seem to behave like 
they have only half length - didn't do much tests yet so it might a 
problem on my side as well.

I'm using the ray only for object selection yet and in that case I 
select the cylinder also when just clicking on the extension of the 
cylinder - but might be another problem as well. Didn't take the time 
yet to take a closer look on that behavior or the code.
