Standalone will not keep Custom Property values

[Douglas Westbrook]

I am working on a application that stores data (codes) and image paths 
as values of custom properties. I tested this weeks ago and it worked 
and when the stand alone was quit it retained the last value input to 
the custom property when the stand alone was relaunched or opened. Now 
it does not work and the stand alone reverts the custom properties to 
the way they were at the time of the stand alone's creation. The data 
input is no longer stored. Does anybody know what I can do to have the 
end user's input or selection retained when they relaunch their 
application?
