[SAC-HELP] ppk zoom error

[Kelly M Liszewski]

 I am using SAC version 101.2 on intel Mac OS X version 10.5.6, and I am running ppk to pick p waves for several stations at a time.  I type ppk p 4 to view four stations at a time, but I can only zoom properly in the first subwindow (at the top of the first four traces plotted).  As I scroll through all of the stations to pick them, when I try to zoom, the zoom function zooms in on the wrong portion of the trace.  Has anyone else had this problem, and does anyone have any advice? 
        Thank you,
