Solved.  Some of the regs, like the T0IR I think, have a nasty 
behaviour of clearing after they are read.  In the debugger I have 
the Registers window open and after a STOP it reads the Regs.  That 
killed the int flag and thus no more jumping into ISR.

So it works now if I shut the regs window.

I was aware of this Read-Once issue, but I guess I thought that the 
JTAG was ported into the CPU and could get at the reg values 
directly.  Kind of like the old bond-out CPU setups.  Not the case.  
Live and learn.
