Windows 10 BDE Lck issue

Hello

I have a paradox 10 app that has been solid for over 10 years in a network multiuser environment. I am aware of all the settings required for normal operation. Recently I had a hard drive crash and purchased a new laptop running windows 10. This laptop runs a ssd as well as a hdd. I have a test environment on this laptop. No outside network comunication. All directories are on a seperate partition. Initially I had an issue that was solved by disabling the drive cache and oplocks. However, it seems to have come back. Initially the app seems fine. But after a bit of use table "add" commands start to fail with either a gpv or application freeze. Clearing lcks temporarily fixes the problem. I am totally stumped.

Deploying the app to the network with windows 7 and windows 10 machines results in no problems. I only have issue in my test environment on my laptop.

Any ideas?

I have disabled cache on both the ssd and hdd. Moving all directories to one or the other has no effect on the problem.
