Section 0.  Known Bugs and How to Avoid Them.

We're working hard to find and eliminate all the bugs in this
software.  However, as of this release we still have a few tough
bugs for which we have not found complete solutions.  The
following list details these bugs and offers recovery and work-
around methods:


	*************************************************

Section 1.  Errata

We have added a new user configuration to M2-200.  

On the M2 dialog you will see a checkbox labeled 
Disable Camera Imager Boundary Constraint.  

When this box is unchecked, the M2-200 will not 
allow beams that are off to the side or too big for the 
camera imager.  This ensures that the beam width computations 
are valid and the results are as accurate as possible.  
When this box is unchecked, the M2-200 will stop 
collecting frames when the beam becomes too big in the far 
field for the imager.

When this box is checked, the M2-200 will collect 
and keep frames where the beam may be off or too big for the 
camera imager.  When this box is checked, it is the responsibility 
of the user to ensure valid beam width computations and accurate results.  

WARNING:  When this box is checked, the M2-200 will 
not stop collecting frames until reaching the specified stop 
point or the limits of the table.  In most cases this is well 
beyond the useful range of beam width measurement.  We suggest 
that you try one run to the limit of the table, examine each of 
the frames, and set a table stop point at some reasonable location 
in the far field.

Section 2.  Notes on Installing and Uninstalling Mē-200

***When you Installed Mē-200 it did the following:
Note: If you changed the drive or paths from the installation
	defaults, then the following paths must be revised per
	those changes.

The following directory structure was created:
   c:\spiricon\m-200 .exe, .cfg, .dll file types
	|_\camera\   <camera>.cam default directory
	|_\data\     <file>.bp#,.rlg,.bmp,.spa,.cma  default
	|_\help\     HELP directory


***If you run the Uninstall Mē-200 it will...
	1. Remove only the files that the Installation program
	added to your PC.

	2a. Display the message "Uninstall completed successfully"
	if all of Mē-200 is completely removed.

	2b. Display the message "Uninstall completed.  Some
	elements could not be removed.  You should manually
	remove items related to the application." if unrecognized
	files were not removed.

	If while running the Mē-200 application, you added
	.bp#,.rlg,.bmp,.spa,.cma files, to any of the
	Mē-200 directories, then those files and directories
	will not be deleted by the Uninstall program.  You must
	delete these files manually then remove directories
	and sub-directories related to Mē-200.
