     66The reason why the shared clipboard does not work is because the shared clipboard handling process inside the guest decided to exit for unknown reasons:
     67
     68{{{

     79}}}

     81In a good working guest, eg. 6.1.2 the picture would be
     82like this:
     83
     84{{{

     98}}}

     100In the guest running the 6.1.4 GAs we are missing:
     101
     102{{{
     103fbatschu  1503     1  0 10:17 ?        00:00:00 /usr/bin/VBoxClient --clipboard

     105}}}
     106
     107Which explains why the shared clipboard ist not working, there is no handler for it.
