AFR Modifier ... bugs reported

[timsiford at hushmail.com]

Dave,

I'll keep that in mind.  Thanks for the advice.  Seems that the problem 
the user was experiencing cannot be reproduced at this time.

BTW - The program will not longer be called AFR Modifier.exe.  I am calling 
it the "Bin Tool Chest" and am converting it to an MDI application.  That 
way anything can be added and it won't be limited to that single option. 
 One of the first things that I want to get in place besides what I have 
already mentioned is a checksum calculator.  Now - I just need to find the 
spare time to get it all done :-)  I'm sure the wife won't be too happy 
for the next week or so ;-) :-)
