Vote problem

It was time to vote so I opened the windows.
Then I saw the Top 100 windows were identical and I wasn't sure I opened both Top 1 and Top 2 sites, so I decided to close both and be more atentive where I click and press the 2 upper vote button again.
But I got back to the vote page and the vote clocks have reset to 12 h

I didn't click on any of them just close them from the toolbar so I don't see any reason that was counted as votting. If closing the vindow presses the vote button implicitely then I am sorry but I just sent 2 void votes.
Please don't be angry at me !
