Calibre 0.4.77 - .78 - .79 won't start up the GUI when using the desktop
icon nor with the folder icon.
It does open the LRF viewer when I want to open a book but thats
the only thing I can get it to do
Removing all traces of previous installs doesn't
seem to help either.
I re-installed 0.4.76 and that works perfectly on both os'ses
