Sednterp 1.09 09/03/06
	Added printout of mean residue weight per peptide bond to
	summary page printed from the sample composition form.
	Added density and viscosity data for DTT to physconst
	database, updated database revision level to 1.1.
Sednterp 1.08 02/09/03
	Fixed program logic errors that could create infinite loops
	from attempted (or accidental) manual entry of anhydrous 
	radius or s(20,w) values, and bug causing crashes from
	attempts to enter values in the last row of amino acids or 
	conjugates on the Sample Composition form
Sednterp 1.07 07/14/02
	Added box on buffer composition form to specify buffer pH. 
	Altered routine for importing amino acid sequences (single 
	letter code) from the Clipboard to ignore all characters 
	that do not correspond to defined amino acids (such as 
	sequence numbers that often appear in sequences copied 
	from the Web). Fixed bugs on Sample Composition form that 
	sometimes put keyboard entries for moles of amino acids or
	conjugates into the wrong column and caused crashes if you
	selected multiple rows within those entry columns. Fixed 
	bug preventing display of shape or axial ratio graphs when
	s(20,w) values are input manually instead of computed.

Sednterp 1.06 06/18/01
	Maintenance update. Fixed error in conversion to s(20,w) when
	vbar was (1) experimental and (2) taken at a different 
	temperature than the velocity data. Fixed error in charge 
	reported on sample composition form (did not include amino or 
	carboxy terminus).

Sednterp 1.05 03/20/00
	Maintenance update. Fixed errors in calculating density of
	buffers containg heavy isotopes, and errors in graphs of
	axial ratio versus hydration.

Sednterp 1.04 01/14/00

	Maintenance update. Fixed bug in buffer composition form 
	that affected only users who do not use a "." as a decimal 
	indicator.

Sednterp 1.03 12/01/99

	Maintenance update. Fixed bug in pasting amino acid sequences 
	into the sample composition form.

Sednterp 1.02 11/28/99

	Maintenance update.

	Fixed bug in solvent density routines. Constant defining 
	density of water at 20 degrees was incorrectly defined as 
	.998324 instead of .998234. This error affects all calculated
	buffer densities, conversions to s(20,w), buoyant masses,
	etc. 

	Fixed bug when temperature of sedimentation velocity 
	experiment was manually set (as opposed to automatic changes
	to match changes to the temperature for equilibrium 
	experiments. This bug affected s(20,w) and so(20,w) 
	calculations.

	Fixed bug in printing sample reports when the number of moles 
	of the amino acid or conjugate is non-integer.

	The program now displays numbers and accepts numerical input
	using the decimal indicator and numerical separators specified
	via the Windows¨ Control Panel.


Sednterp 1.01 10/30/97

	Maintenance update.

	Fixed bug in reading sequence files with 3-letter codes.  Now 
	properly generates a single-letter sequence for storage in 
	the database.

	Fixed bug in calculating theoretical absorption spectra from 
	the composition.  The contributions from Phe, and any 
	conjugates for which spectral data had been added to the 
	database, were not being included on the graph.  This bug did 
	NOT affect the calculation of extinction coefficients at 
	280 nm.

	Revised Help file to clarify that sequence files must have 
	the file extension ".SEQ"

	Minor changes to graphing window: addition of status bar, 
	minor bug fixes in graphing package.
