when you are using pekwm as gnome WM and you have any window open and try to edit a file name or Icon name that are in the desktop you can't because the window open steal the focus ( or the desktop item don't never get the focus ).
still happen in pekwm 0.1.12 , the focus model is the default one ( focus following the mouse )
How is your focus model configured and does this issue still exist in 0.1.12?
