Input[] puts up a special dialog window for entering an expression:

InputString[] puts up a special dialog window for entering a string:

Possible Issues  (1)

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:
