How to submit bug reports
Did you encounter a bug in SumatraPDF?
Check in latest pre-release build
First, see if it still happens in latest
. It's possible that a bug has already been fixed there.
Create an issue
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 on the issue
field). Without a test document we rarely can make progress on fixing
Provide reproduction steps
Often the bug only happens in a specific scenario.
If possible, please provide step-by-step instructions for reproducing
