comment How to create internally optimized expression for computing with high WorkingPrecision?
performing arithmetic operations in the right way can reduce round off errors. One important example is use of HornerForm (a built in function) for computing polynomials. Most text books on numerical methods show a few other tricks for specific cases. It's all about avoiding catastrophic cancelation, which is the loss of precision due to subtracting numbers that are nearly equal but not close to zero.

It might work better if you make jacobianMatrix a CompiledFunction. That will help if FindMinimum uses MachinePrecision to get close to the optimal solution, and switch to higher precision for fine tuning.

Yet another scoping construct that I didn't see mentioned is DynamicModule.

For years I have wondered why Wolfram hasn't included each steam table as an InterpolatingFunction.

comment A good way to manage code in a complicated CDF?
I saw SaveDefinitions before, but couldn't remember what it's called. I think that's the solution to my problem. Although I haven't had a chance to try it. I would accept it as an answer if you entered your comment as an answer.

comment Creating a Tooltip that knows what platform is currently being used
This is the best criteria to use. However, failure to use Dynamic (See RM's solution) is real cause of my problem.
