Potentially dangerous/unsafe ways of interaction

Potentially dangerous/unsafe ways of interaction

When we click on the 'Send' button without subject you are throwing open a Scripting Input Box. You may not be aware that web browsers block this  off for security reasons. 

Can you have this changed to a normal DIV or a plain vanilla confirmation?
