Problem with the window duration

[leon2225]

Hey,
thank you for developing such a great tool, it is really fun and easy to use and has a quite big bandwidth as well!
I do have one issue though – for some reason, the plotted diagram doesn't start to 'scroll' when it should be based on the configured window time. But instead, the values do never move out of the visible area or get deleted (What would be the expected Behavior if I had selected “no window” in the upper-right corner).
In the Image below, you can see that there is data for a timespan of around 40 seconds, while actually, there should only be data for one second.

I hope that you can help me with this issue and that it's not me who is doing something stupidly wrong.
