Subject: Type 1 error - ignore if you already know about what it is

Folks,
Anyone who has not heard the answer to this FAQ should read this:
Why does my ...
Application unexpectedly quit?
Finder report a Type 1, 2, 3, or 28 error?
Finder report an F-line error?
Finder report a BusError (Type 1)?

All four of these happen basically due to any of the following problems:
Your desktop file is corrupted
Your PRAM is corrupted
An INIT conflict
A fragmented hard drive
Incompatibility with machine or system 
Lack of math coprocessor (usually followed by a Finder error 90)

Solution:
To uncorrupt (or rebuild) your desktop file, after the About this Macintosh
screen
disappears during startup, press the Apple and Option keys simultaneously. 
This results in the loss of file comments in the Get Info of the Finder. 

To uncorrupt (or ZAP) your PRAM, hit the Apple, Option, P, and R keys 
simulataneously when your Mac starts up. The screen will blink, and when the 
Mac is done loading, you will have to reset your control panels to your 
desired settings. Also, if you don't want AppleTalk on, zapping the PRAM turns 
it on. To fix the AppleTalk problem, just enter the Chooser DA, and turn it 
off.

An INIT conflict. Extensions Manager 2.0.1 is Free and available at many sites 
on the Net and at Mac BBSs. It is made by Apple, and allows you to select 
which INITs (Extensions in System 7) are loaded. Sometimes the conflicting 
INIT can be loaded by itself without any problems. If you isolate the 
conflicting INIT, try renaming it either the last or the first name in the 
alphabet of INITs. Entering a space in the name puts it before the other INITs 
that begin with a number or alphabet character. Control keys are even earlier.
Finally, all programs that do not require extensions loaded, will work fine 
with all extensions off. To turn off all extensions, press the SHIFT key upon 
startup.

Two utilities are available commercially to fix fragmented hard drives: Speed 
Disk (by Norton), and DiskExpress by Alsoft (I forget who bought Alsoft, but 
somebody will probably reply to this FAQ mentioning who did). Turn off all 
your extensions except the DiskExpress control panel (if using Alsoft's 
product), when you do a defragmentation.

If none of these solutions appear to fix the problem, then you need to contact 
the author and tell them what System you are running, the RAM installed on your 
system, whether your machine has an FPU, and what machine you are using.
The system can be found by selecting About This Macintosh (or About Finder) 
>From the Apple Menu when you are in the Finder.
The RAM installed is also in that window.  The author can tell you if the 
software is compatible with your machine.

All LC machines lack FPUs (except those that have had them specifically
 installed). 

Above all, read the documentation that comes with the software. Many time the 
author specifies what is required to run the software.

Hope this helps.
