Hi everyone

I'm analysing about 13 HSQCs in one window and whenever I navigate to a 
peak via selection from the peak list, turn a spectrum on or off, or 
change the contour level, the window goes blank for about 5 secs and 
then redraws everything.  They are all nmrPipe .ft2 spectra.  The 
following message appears in the terminal:
Exception in Tkinter callback

Any ideas as to the problem

Regards
