Thanks for replying. I have a lot of third party plug ins. I am just frustrated trying to figure this out. I wish Pro Tools had a Plug in Verifier like Logic. I put these in the unused folder

Auto Tune 5

SpeakerPhone 1.11

Eventide Anthology 2

URS 1975 Channel Strip

Waves SSL V6

 and I haven't had the problem scince. I will try yours again

Thanks
