See a previous thread for an explanation of PIC24/PCD behaviour in this regard: http://www.ccsinfo.com/forum/viewtopic.php?t=40072&highlight=nstdis

I guess, CCS developers thought, they should better disable interrupt nesting. As in many cases, the did not think about possible side effects or verified continuity of previously achieved compiler function.
