[comp.sys.mac] MultiFinder and DA

sivagnan@handel.ColoState.EDU (Vasanthan Sivagnanadasan) (06/13/88)

 I am running MultiFinder 1.0 under finder 6.0 System 4.2 on my Mac SE
with 1 Meg of memory. When I open a DA from the apple menu I just get
the beep and the DA will not open. But if I just run the finder it
opens.  How can I solve this problem?

Hold down the command key to open a DA when memory is low.  The key
causes MultiFinder to start the DA in the application's partition
(preallocated memory), not in some new allocation (that fails because
the heap is nearly full).  This is documented in your macintosh user's
manual, I believe.

If this doesn't work for you, you might try switching to an
application with plenty of free memory (go to the word processor and
close all your windows?) and try it again.

There are really two ways of dealing with this, the first being the most
painful.  The painful method is to get more memory.  The not so painful, but
annoying way is to hold down the Option key when selecting the DA from the
Apple menu.  This will cause the DA to load in the heap of the currently
executing application.  Not holding down the Option key causes the launch of
the DA Handler.  If you are running some application along with the Finder
under MultiFinder, it is quite likely that there will not be enough memory to
load a DA such as DiskTop or Acta, which require a fair amount of memory to do
their magic.

A note to those using Suitcase--  If you hold Option while selecting
the Apple menu, you don't see any DAs, just the application list.  The
trick is to FIRST select the Apple menu, THEN press Option, and hold
it until you have let the mouse button up over the DA selected.

[ computer beeps under multifinder when one tried to load DA ]

I had this same problem when I first installed multifinder on my Mac. Not
having the manuals, (which cost $$$) I was in the dark. It turns out that
Multifinder needs a system file called 'DA Handler' which is loaded much
like an application and then the DA's are put in this process's heap.

Without the file, multifinder looks for it, and not finding it, simply beeps.

If you were out of memory, the DA handler would tell you so.

You should have this file as part of the Multifinder system disks.
If not, I suppose I can send it to you. (That's ok, right?, or is that not
all right any more?)

Good Luck,

I think you mean the OPTION key, not the command key.
