comment Removing zero values from ordered pairs
@Mr.Wizard Just a sidenote: I'm not sure Equal is the best case for zero-testing, as it does not return a boolean for nonnumeric input. Therefore Equal could pose a problem when e.g. picking out nontrivial solutions of Solve, e.g. Cases[{x -> 0, x -> k - h/r}, _?(Last@# != 0 &)] vs. Cases[{x -> 0, x -> k - h/r}, _?(Not@PossibleZeroQ@Last@# &)].

comment How to control dependent PopupMenus?
@Subbu I've greatly simplified your question: most of it was just styling and sugar. You would get much faster and better answers if you were to put more effort into disassembling your problems to the core. In this case, it could even have been reduced to a two-interrelated-controller problem using the second argument of Dynamic of which here and here are a few answers. (yes I am aware of the date)

comment Should Read[] not close its Stream?
ReadList reads the whole content of a file, so it makes sense to close it afterwards, while Read only reads the next entry in the file (be it a number, line, record, whatever). This is by design.
