Did you encounter a bug in SumatraPDF?
Check the latest pre-release build #
First, see if it still happens in the latest pre-release version. The bug may already have been fixed there.
Create an issue #
If the problem is present in the latest pre-release build, please create a bug report in our issue tracker.
Provide a test file #
Does it involve a specific PDF (or CHM or XPS) file?
Please attach it to the issue (try dragging and dropping it onto the issue field). Without a test document, we can rarely make progress on fixing the issue.
If the file (or other information) is confidential, you can e-mail it directly to [email protected] (Krzysztof Kowalczyk, SumatraPDF’s main developer).
Provide reproduction steps #
Often the bug only happens in a specific scenario.
If possible, please provide step-by-step instructions for reproducing the issue.
