+## Click Commands are not Executed
+**Problem:** Some `click-*` commands are not executed when the bar is clicked. This is a bug that is triggered by the `click-*` command producing output on `stdout` or `stderr`.
+
+**Workaround:** The `click-*` command must not produce any output, so redirect any output to `/dev/null`. This can be done by appending `>/dev/null 2>&1` to the `click-*` command.

+This issue was discovered in [`#916`](https://github.com/jaagr/polybar/issues/916).
