I just purchase an SE/30 with 40MB hard drive and I love it.  It's sleek
and fast...

Anyway, everything was working fine until I started it up under
MultiFinder.  Suddenly, I could hear a very high-pitched, barely audible
whine coming from the Mac.  Upon doing some testing, the whine stops
when I hold down the Mouse button (such as a selection box in Finder) or
bring up any dialog box or DA (ie Chooser).

This noise does not occur when MultiFinder is not running (ie just using
Finder).

I am using a fairly standard system (nothing to wierd software wise). 
Also, I installed an extra 1 Megabyte RAM using 4 256K SIMMS giving me 2
Meg total.

Why is it doing this?!?!?!?

Any comments/suggestions are welcome.

Thanks,
ross
