[Closed] How to make button response when rendering?

Hi,
I am looking for a way to get response when rendering for a long time,just look codes below:

rollout test_response "test_response" 
(
 button press_me "press me" 
 on press_me pressed do print "Is responsing..."
 )
createDialog test_response 

when max is not rendering,this button can response,but,when you’re rendering,all buttons are busying…none of them can response,so I just wondering,is there a way to handle it?
