I may have identified a small bug with the WaitForSpeech command.
The command works fine when coding inside a script manager console but fails to work outside the editing environment.
I have also tried this inside a stand alone script window
Both methods hang with a partially drawn dialogue box with "Waiting for Speech..." visible. It eventually switches to "Not Responding" which of course forces me to close EZ-Builder.
I am using Win10 and the latest version of EZ-Builder.
