Before applying the patch, try to open the GUI without a .dat file. Then 
try to change the marker by pressing one of the marker's buttons. This 
will try to update the labels of the time axis. But because no data is 
loaded and nothing is plotted you will see only zeros at the place where 
the time axis is supposed to be plotted.

Thanks!
