From the Changelog of openbox-3.4.7: * Change _NET_ACTIVE_WINDOW messages to not change the current desktop, but to bring the window to the current desktop instead. This is the industry standard policy This results in netwmpager not working correctly with newer openbox releases (details in the the bug linked). I'll attach a simple patch that fixes the behaviour. I've sent it to the netwmpager upstream but no response so far.
Created attachment 148194 [details, diff] one-line fix for netwmpager
Should be fixed in -r1. :) Thanks for the patch.
