Igor 10.0 Filter "dialog" bugfix

The Filter "dialog" in Igor is created by a procedure file that I revised for Igor 10.0 to allow filtering multi-channel waves.

In doing so, I broke the dialog's more common application of filtering one-dimensional waves; they don't appear in the Apply Filter tab's wave selector widget.

You can fix this problem (and keep the multi-column filtering improvement) by replacing your FilterDialog.ipf file here:

Igor Pro Folder\WaveMetrics Procedures\Analysis\FilterDialog.ipf

with the attached file.

This version will ship with the next release of Igor 10, and is also fixed in the latest Nightly Build: https://www.wavemetrics.net/Downloads/latest10/
