Cortona can be turned off (I am in Spain, it is not available here). The only issue I have with Win10 is with some very specialized debuggers; other than that I am quite happy with it. I do experience some issues with search, particularly that it does not find items that are in the start menu, even after re-indexing. Windows 7 and 8 are bothered with the same though.
Isolation of sub-problems is a good strategy in any flowsheeting application. Typically a flowsheet has three kinds of problems: 1) bugs, best solution: report and they will get resolved, if I can reproduce them, 2) unfeasible problem specifications: possible solution, put the log in verbose mode and look for debug messages on which variable has the higher residual. Check what influences that variable. 3) convergence issue. Best solution is to specify a reasonable initial guess; as with (2) look at the verbose log and the residuals. Also often used: solve with recycles not closed. Close recycles once they become reasonably estimated. And as you do, try to start with a simpler sub-problem.
Your problems are noted and I hope you will report further on them.
