Bug 362128

Since 5.6.2, my task manager bar is always restored to screen 1 (which is left-of screen 0) instead of screen 0. I can drag it back to screen 0 (and the lastScreen config entry is updated correctly), but on restart it's back on screen 1. I guess this could be related to this commit:

    insist to have lastScreen -1
    
    never risk to go in a panel by itself
