WaveLab Update 10.0.50:
If you zoom in (or out) with the keyboard at the position indicator in an audio file, the displayed waveform jumps to the left and right at some zoom levels. Correctly the display of the wave should expand (or contract) equally on both sides of the position indicator with each zoom level. In other words, the waveform visually should always indicate the same sample at the current position as you zoom.
In 10.0.40 this was correct, in 10.0.50 now it is not.
