Constantly having to hit command+H because photoshop won't keep my settings set.

every 30 seconds or so photoshop brings up the "extras" setting so that I am seeing the borders, layers highlighted, etc. I have this setting turned off and have never turned it on, but now no matter how many times I turn it back off with command + H, within 30 seconds it is back on. this has been happening for nearly a month now and is severely impacting my workflow and is all-in-all extremely irritating. please address.
