I've just installed a bunch of updates yesterday, and since then my dmenu and morc_menu have the following problem. When i hit mod+d or mod+z the dmenu or morc_menu come up, but then on the next key press they disappear. Even if I hit enter, it doesn't launch the highlighted app. I can however click on the items with the mouse.
Most frustrating, does anyone know what the problem might be or how I would go about debugging it?
