Yes, the MARKER and the tasker are incompatible, since the task
chain is independent of the MARKER. I guess the thing to do is to
restore the task chain to the default value, killing all the tasks,
and THEN using the MARKER defined word to get you back to square one.

Yes, the SOUND words will make their way back in. Sorry about breaking
the old code - I guess my user base (you) wasn't big enough that I
got too many complaints :-)

Are you putting msWait (or the definition that calls it) into a :NONAME
task like in the tasker example. Just running msWAIT interactively will
not put anything in the task list and PAUSE will just go away into the
ether...
Thanks for being a patient guinea pig...(is that a common term in the UK?)
