Administrative console interface is projected the way, that user not required to perform dbl-click to do anything. But there are some old-school users, that still use dbl-click on toolbar buttons.
For those users we've implemented protection, that one button/form could not be submitted more then one time in 500ms. But still one in a year some users were able to perform dbl-click where 2nd click was 500ms after 1st click. This resulted in double form submit. Usually double submit is not a big problem, but in some case data could be lost (based on what actually happens after given form is submitted).
