VS Search

At the AAVSO meeting Doug Welch introduced me to the VS Search option.  Great tool!   But I have had a problem using it.

I have images from smaller CCD (1.3Kx1.4K) and a largerd CCD (2Kx2K).  VS Search seems to work great on images from the smaller CCD but when I try to run it on the images from the larger CCD, it appears to fail and return nothing.  The failure of VS Search appears only to occur when I try it with the larger CCD images.

I'm happy to provide images that work and don't work to anyone who wants to diagnose and fix this issue.  Thanks.
