Hi! I use six spaces on my MBP and I use control+1, control+2, ..., control+6 as keyboard shortcuts to navigate through the spaces. This works fine for spaces 1 to 4, but I can't access spaces 5 and 6 with these shortcuts. I can only access them through the drop-down Spaces menu in the menu bar or by dragging windows to the edge of the screen in order to get to the next space. To try to overcome this I went to the Spaces preferences and subtracted and added a row of spaces. After doing that, it works fine. Until I restart or shutdown and boot my computer, at which point I have the problem again. Does anybody else have this issue? Any help is appreciated. Thanks in advance!
