I'm not certain how exactly the dialogue would have been detected in TC12, but those types of pop up dialogues may be getting detected as an unexpected window in TC14, which may cause TC to ignore those windows, leading to some problems in detecting the objects.
if you go into tools>current project properties>playback
you could perhaps try tinkering with the on unexpected window checkboxes (namely by turning off the send close command and press esc) and see if you have any better luck with TC interacting with the popup dialogue
Lastly, it depends what that dialogue is exactly. If it is a microsoft windows based pop up dialogue, you may need to enable MSAA * support to interact with those yes or no options (say like download a file dialogue)
Keep us updated on any progress :)
