Elevator trim problem

I have an elevator trim problem with ALL of my CFS2 aircraft.
Just a single keystroke, no matter how fast will change the trim drastically and I'm unable to get 'em lined up level.
These same aircraft wok ok in FS2k2 so I really suspect the CDS2 engine and not the config. - but I could be wrong.
Is this a generic problem with a fix, or do I just , have to live with it ?
Thanks,
