I have a reproducible issue with integrated git: when I deliberately change a file under version control and try to commit from the command line git picks up the change. However when I run Git->Commit on my project root folder from the IDE I get the message "No changes detected.", whatever I change. The IDE can start git and there are no error messages in the Version Control tab.
There is one incident that might not be related: The IDE used to be able to start git from the path. This stopped working and I had to point the IDE to the full path of the git binary.
Hope someone can help out. Let me know if you need more details.
