Output Window Looping not working

Can anyone help me out with what I screwed up? When I click the Loop icon on the player output window of the color page, the Loop icon turns red but at the end of the clip it advances to the next clip instead of looping back to the beginning. It's obviously something I did wrong because it's only in the current project that it is misbehaving. I've tried it in older projects and it is working as it should. I've closed and reopened the current project several times but the problem persists.

V17.0 Build 39

Okay, I'll give that a try right now. Thanks Jim.
