When "Enable speech" is recognized, exception is thrown

[okeefm]

Hello,

I'm running the version of your EESpeak software currently listed on the ZarthCode blog on my computer, which is running Windows 7 64-bit. Speech recognition works quite well, but when I try to enable speech, I get so far as hearing "speech enabled" before an exception is thrown with the following text:

System.InvalidOperationException: Cannot perform this operation while the recognizer is doing recognition.
 at System.Speech.Recognition.RecognizerBase.RecognizeAsync(RecognizeMode mode)
 at EESpeak.MainForm.speechRecognizer_SpeechRecognized(Object sender,     SpeechRecognizedEventArgs e)

Let me know if you want any more debugging info from me.

Note: the same exception is thrown when I try to turn on metric prefixes.

Going to try to duplicate this, I suspect there's a bit of a logic issue when handling recognized speech - or it could be connected to he "loop" issue from awhile back.
