Unfortunately the simple answer is that if the program does not
implement the accessibility API this sort of thing is an incredible
paint. Even worse is that the older .net winforms gave a great deal
of support for these events natively but the newer WPF makes each
program do much of the work itself.
Honestly, depending on the program it might be more productive to
contact the application developer and explain the issue. Adding such
support to the program code is usually far easier than writing scripts
for this sort of focus tracking. And if the program developer does it
then it does not matter what screen reader the user has, unlike with a
script solution which is tied to a particular product.
