'it is a unsign applicatoin to run', everytime i Need click 'YES", otherwise I cannot processing.

by the way, how can I setup it will auto ans? like 'never show it again' or ' always run it'?
because if in win IE, I have a box for it.

System Preferences->Security & Privacy ->Allow applications download form:
(第2个个好像较第3个个 安全d )

as I Know, this option 'allow downlaod application' which is for installation only. Mean if I download /install some software, it will block.

and I am sure I didn't enable it. Otherwise I can't install any software.

seem the ebanking need run the Java, but I need to click 'RUN' everytime.

If in Windows IE, I can click 'always run'.
