TRS 2006 surveyor troubles

[Wyonate]

I have TRS 2006 and in surveyor after I make a industry I run a few trains and thenshut the computer down.  When I come back my locos won't hold a throttle postion, it returns to 0 notch or won't stay in any given notch.  I do not understand why!?!?!?  Any help?   Thanks.

I've seen the throttle return-to-zero problem when using locos that require a separate startup sequence.  Are the loco's in question SD70's by any chance?
