Welcome to the help and discussion forum for the Integrative Genomics Viewer (IGV). If posting about a problem, please include:

The version of IGV you are using, and your computer operating system.
What you did. If the problem happens when you open a file and/or view certain genomic coordinates, attach the file* (or provide a link) and specify the genomic coordinates. Please DO NOT paste the contents of your file into an email or in the group's web interface, as files are whitespace sensitive which gets lost when sent in the body of an email.
Your igv0.log file. It will be in <your home directory>/igv.
