Ghost Miniature & Banner Problems

I keep having a miniature i have used before re-appear in the same place every time i open my table. it goes by the name of "Policeman" ; It appears in the upper right of the board.
My second problem is the inability to change my banner. I have created a 550x80 pixel banner in photoshop. After the file didn't work i converted it to Paint.NET file format. I'm not sure if these formats are not supported but they both didn't work. I will try other file formats of the same dimentions to see if i get it to work in the meantime.
My browser version is: (do not change)
Mozilla/5.0 (Windows NT 6.1; rv:13.0) Gecko/20100101 Firefox/13.0.1

Yeah nevermind about the banner, i converted the file to a .Png and it seemed to work flawlessly. Still have that ghost miniature problem though.

This should be fixed now. I'm also working on a more re-usable fix in case it happens to someone else.

I'm also having the trouble with the miniatures on my table. I can delete/kill them as the GM, but the rest of the players still see them on the table... for every scene I load.

And every time I refresh the page/table, they show up again. :(

I can move the miniatures around, but all that does is create a copy. The original miniatures are still in the same spot on the other player's window.

Hi amandalyn, I just reset your miniatures/battlemat, so it should be fixed. I guess I still need to figure out why it was doing that. Thanks

Thanks a lot!
The only thing I can think of... is that they were from the previous session's play. I never removed them from the board before closing my window. And the next day, they were there... and wouldn't go away. xD
