Reproducable bug: When I add a new Section on the right hand corner of the screen, then drag this Section to the right to make it longer, more often than not this Section will then grow forever. On the Controller I can see the "length" parameter constantly rising while the Software is locked up, mouse pointer remains as double-arrow. Only solution is to delete the forever-growing Section via Controller. Maybe it's due to my widescreen monitor, I don't know, but it happens on a regular basis. Not gonna report this to NI directly, I'm feed up with their "support".
