You can report bugs in our bug tracker - Mantis. This will make it easiest for Galaxy developers to keep track of the bug, and, if necessary, ask you for follow-up information directly.
When submitting your report, make sure to attach Galaxy's log files, which can be found here:
- Windows - C:\ProgramData\GOG.com\Galaxy\logs
(You have to make hidden and system folders visible in order to get to these files)
- Mac - /Users/Shared/GOG.com/Galaxy/Logs
