Actually, the buttons for "Allow" and "Deny" and the "Remember this decesion" checkbox are overlapped on each other in the Tea Timer alert box. This is a bug in the 1.4 and this is to be fixed in next update. Until then, you can "guess" the location of the buttons and click them in Tea Timer or you can disable the Tea Timer.
To disable Tea Timer, go to Mode Menu > Advanced. Then, click "Tools" > "Resident" button in the left pane, and uncheck the "Tea Timer" option.
Here's a screenshot of the buggy Tea Timer and "correct" Tea Timer:-
