Constantly locking, have to enter my password over and over.

I have 1Password installed as a Chrome extension, and lately it's doing this thing where sometimes it makes me unlock it over and over. Sometimes every few seconds it locks it again. And then it'll be fine for a couple of days, and then it'll start locking it repeatedly again for a while. Anyone else have this issue?

I'm using the Comet browser, but it's based on Chrome and works with Chrome extensions, so that shouldn't be the issue I don't think.
