1. "Contact" on "My Iczer" page is supposed to open a new window. This is not a bug.
2. The white block is a bug. We fixed this right before the launch, but when we switched the test server to the actual server, the fix didn't get carried over. We've reported this to Japanese Alteil staff, and should be fixed in a couple of days.
3. If you're just talking about the color, Blocklist is supposed to be gray. Or are you talking about how you still can see the white box (bug #2) when Blocklist is selected? If not, I don't think I understand what you mean...
I feel bad asking you this, (since you even attached a picture) but can you describe more about the bug #3?
