- Which version of IGV are you currently running? And were you using a different version when it was last working for you?
- Are you running an IGV that comes with Java, or are you running the IGV that uses the Java you have installed on your system? If the latter, did you update your Java recently?
If you are not using the latest version of IGV, please download the latest version with Java (here's a
link to the downloads page) and see if it still behaves the same way.
If there's still a problem, please send us the log from the latest run of IGV. It will be in a file named igv0.log (or igv1.log) located in the "igv" folder in your home folder.
