COMRETURNERROR is the most important. Yes each error only affects a thread. There should be no need to reduce thread counts, use those SYS commands or reset as far as I know.
Feel free to grab the source from ActiveVFP(like the error handler) if you want to re-use the classes. Have you gotten foxisapi working with an mtdll yet??
