[Lowfer] Argo and Spectran under Windows 8.1

[JD]

Interesting information, Cliff, but I think it demonstrates precisely why 
the example was sound.

It's a direct answer to what JB was asking: why WOULDN'T an application 
written for one version of Windows necessarily be expected to work on a 
later one?  Because Microsoft sometimes changes the rules.

This particular change may have been documented well enough for active 
developers.  But we mere mortals being forced to "upgrade" to a later OS, as 
Mark is having to do, are less likely to hear about such things until after 
we suddenly encounter a problem with our preferred software.  So, it pays to 
ask about others' experiences.

(In my anecdote about WSPR, note that I had _not_  upgraded from a pre-Vista 
version of Windows.  The computer came with Windows 7, and my first 
installation of WSPR worked just fine on it.  Whether it _should_ have 
worked at first or not is an interesting side question.  Did somebody at 
Microsoft slip up and omit the file restriction in the first release of 7, 
then correct it?  At any rate, IMO, it's worth remembering that periodic 
updates alone can sometimes break an application, even without going to a 
whole new version of the OS.)
