I've got FileMaker Server Running, and if i connect to the ServerPage and then if i try to start the Admin Console, my MacBook Air downloads a .jnlp file and opens it with TextEdit....

If I do the same thing on my iMac, it downloads the file, starts it with Java Web Start and Java is opening the necessary console....

Does anyone know why??

The Air asks me, what program to use to open it, and offers me Java Web Start in the dropdown. But even if I choose it, the air takes the TextEdit
