Hi, Michael! We have found the problem and expect to have a fix soon.
Thanks for your brilliantly clear report! -Galt 5/3/2012 3:26 PM, Michael Hoffman: > Hi all, > > I have been trying to view some custom tracks, which are made of bigBed > files with a small number of features but lots of blocks (exons) for > each feature.
