[comp.sys.mac] What does a flashing menu bar when booting MultiFinder mean??

Seemingly out of the blue, my SE wouldn't boot with MultiFinder as startup.
(Finder v6.0 Sys v4.2)  Using the Finder only worked fine.  When trying to
start with MultiFinder as startup, the menubar (with Aplle icon and
appropriate menu entries displayed) simply flashed on and off.  Very strange...

Moving random things (such as inits) in and out of the System Folder seemed
to cure the problem.  I then rebuilt the desktop (*under MultiFinder*),
configured the System Folder with exactly the same contents as it had prior
to this incident, and everything has been fine since.  Simply rebuilding the
desktop with the Finder was not sufficient.  

I have to believe there's a reasonable explanation for this behavior.  Does
anybody know....
   1) What would have caused this bahavior to occur??
   2) What is a flashing menu when booting MultiFinder symptomatic of??
   3) Why would it make a difference if I rebuilt the desktop with the Finder
      versus MultiFinder??

Thanks for your collective time...
