Documentation : How to submit bug reports

Did you find a bug in Sumatra? Please create a bug report in our issue tracker .

Does it involve a specific PDF (or CHM or XPS or …) file? It’s important to provide us with a file that shows the problem by e.g. by attaching it to the issue or uploading it to ge.tt and sharing a link.

If you’re using the latest release version, please try the portable prerelease . It’s possible the bug has already been fixed.

If the file (or other information) is confidential, you can e-mail it directly to [email protected] ( Krzysztof Kowalczyk , Sumatra’s main developer).
