Question: My Dictation Properties and/or Change Dictation State dialog box is too small, how do I make it bigger?
If you are unable to make changes to the Dictation Properties and/or Change Dictation State because the dialog box is too small, it’s most likely a result of your screen resolution being too high (1920 X 1080).
To fix: 

1. Close the Philips SpeechExec Pro software by going to File > Exit.
2. Browse to the logged on user’s local Application Data folder.  You can access the App Data folder in two ways.
A. Going to C:Usersuser nameAppDataRoamingPhilips SpeechSpeechExecLocalPrefs
B. Go to Start > Run and type: %appdata% PhilipsSpeech>SpeechExec>LocalPrefs
3. Once you locate the LocalPrefs folder, delete it.
4. Launch the application.  Dialog box should be fine now.
