The red One Click flyout can no longer be controlled by the user. Those options were removed by the TS a version or two ago. The checkbox is to hide Snagit but doesn't impact OneClick.
There's no longer a way to do what you want David unless you revert back to an older version. V10, I think allowed for the flyout to stay out for a long time but I don't think any of the versions allowed for it to permenantly to stay out. One click is designed for single captures. For multiple captures, if I'm reading you correctly, you can do a profile timed capture but that depends on exactly what you are doing.
