The Best Mac Site-Specific Browser for Google Docs

So here’s a mystery. My previous Google Docs site-specific browser was named “Google Docs” (clever, I know). While writing this article, I kept the Coherence SSB separate by calling it “Coherence Docs.” But afterward, when I’d settled on Coherence, I renamed (or recreated, I don’t remember) the SSB as “Google Docs,” replacing the Epichrome SSB.

It has been working fine, exactly as I described in the article. But here’s the mystery. Whenever I restart, the old Epichrome SSB replaces the new Coherence SSB every time. The Epichrome SSB has a modified date matching the restart. There’s no login item that would do this, and I can’t think of any other way that an app would be replaced on restart.

Restoring the Coherence SSB from Time Machine puts everything back the way it should be, luckily, but I’m currently at a loss as to what could cause this.

Ideas?
