Flex GUI - MDI Button

When the mdi-button is doubleclicked accidentally or just clicked multiple times in a short period, 
the mdi command is executed , mostly uwanted, multiple times. Is it possible to lock the button for
0.5 second or an adjustable value? 

Thanks for reply. I was testing with a value of 200 instead 400 default.  Then i recognized the mdi commands are qeued, so there is no escape from executing every button press. Now i try something with a normal pushbutton and use the pythonmodul. creating a timestamp on each button press and get the difference, only execute the command if result is >=7. I am still testing
