x axis rescaling when averaging waves

Hello, I am using igor to average waves. Both of the waves I am averaging use an x axis scale of 1-20,000ms, but when I average them using the package, it rescales my waves to 1-1000ms. Is there anyway to fix this? This makes curve fitting values completely wrong.

Thanks

We found that Igor 6.37 shipped with a bug in Waves Average.ipf that may be at fault here.

Try the attached version (which will ship with 6.38 soon).
