Running Keyclone as administrator does not, by itself, solve the issue. Two of my five computers still have a tendancy to tab to Windows.

The working solution I have so far is that, when this problem arises, I close Keyclone and launch again (as administrator) until Keyclone is stable. I may have to close and launch Keyclone several times for this to work.

I have never had this issue before and v1.8 worked perfectly so it's all very strange.
