hm...I have no idea how it works then, as I've never tested it purposely. I just know that I've let often, unconsciously left MH open in a tab while either working on other things or being away from the computer. I think dispo and style tried to test out in the past, though.
Lol MH is the first tab that pops up when i open my browser. And i always use that first tab to surf. Ima switch it 2 the second or third since i seem to never use those.
