Hello,
I wanted to let you know that our programmer committed a fix for this and it is now included in our McIDAS-V 1.7beta1 nightly builds. If you are interested, you can pick up a nightly here:
http://www.ssec.wisc.edu/mcidas/software/v/unstable/ (the login and password are both 'mcv').
Note that our nightly build is automatically generated every morning with the previous day's programming changes, so not everything in the nightly has been fully tested, meaning you may find bugs. If you give the nightly build a try and run into any problems, please let me know. I did test this fix with several of the various ways you can order the VICMO files from NOAA CLASS (pre-aggregated, de-aggregated, and geolocation separate) on my Windows 7 machine and it appears to be working well.
Thanks again for bringing this problem to our attention -
Bob
