Thanks for the quick response and suggestion.
I went through another complete uninstall; this time including the Documents\A2A folder. reboot and no change in behavior.
Re-installed Accufeel, reboot and still no change.
So I then reinstalled the pre-release update re-booted and; that's right, bounces are still there.
So... unless you have other ideas or someone else has the same bounces, I just don't think this is an Accufeel problem or a Carenado problem. There must be some other cause. And, I refuse to believe old age has contributed in any way to this discovery; so, don't even think it.
P.S. I should also say that Accufeel is the one add-on that finally convinced me to commit to FSX. Bought a new computer went through weeks of set-up and tuning and I am thrilled with the results. Accufeel is one of the best enhancements I have ever added to my sim experience. Thanks to everyone for the hard work and dedication to realism.
