SF does not stay in menu bar anymore.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install of 1.6.6 version on Mac os X 10.8.
2. Launch SF through Spotlight or directly from the Applications folder.
3. SF icon appears a few seconds and then disappears.

What is the expected output? What do you see instead?
Icon supposed to stay in the menu bar and then I can open the SF menu. Instead 
of this, the SF icon disappears a few seconds after appearing. Sometimes I have 
time enough to select in the SF menu, sometimes not.

What version of the product are you using? On what operating system?
SF 1.6.6b, and Mac os X 10.8.

Please provide any additional information below.
- The thing is weird cuz yesterday I discovered SF, installed it and mofified 
preferences in Audio and Midi menu. SF is great and works well. And then, in 
the evening, the sound was weird (huge grgrgrgrgrgr) so that I was obliged to 
change audio and midi preferences to original settings. Today, after starting 
MBP, the problem of disappearing icon began.
- I have tried to uninstall SF but the pb remains.
- I then saw that the KEXT file does not exist in the Extensions folder (which 
Extensions folder by the way?).
