OK, I uninstalled, rebooted, reinstalled and still quick hide isn't working automatically on reboot.
Uninstalled with iObit uninstaller, cleaned registry, rebooted, reinstalled. Still no joy. And my fences were remembered, which shouldn't be the case after a registry clean.
Reverted to the 3.03 release version, and still the problem exists. I am assuming the problem is with the Creators Update?
