CancelButton[] implicitly uses DialogReturn[$Canceled]:
Input[] puts up a special dialog window for entering an expression:
InputString[] puts up a special dialog window for entering a string:

DialogInput blocks the queued evaluation channel, preventing queued controls from working:
Some values of SynchronousUpdating also use the queued channel and are blocked:
For Manipulate, the default value of SynchronousUpdating must be changed for it to work:
Scheduled tasks might not run while the queued evaluation channel is blocked:
