Windows, Focused Control and Keyboard Input problem

So I have a web based game, and recently converted some of the GUI to use windows. It was pretty straight forward to get them working, and I had found a snippet in the forums about using GetNameOfFocusedControl in combination with Event driven input to do things like - only accept enter for a chat message when the chat text field in the chat window had focus. Dropping this in resulted in perfection. Then I went home over the weekend and for fun tried my game from their on a windows machine, I tried with IE and Firefox, and the enter key was no longer being registered and I couldn’t use my chat. Here is the code in the chat window:

	// Make the contents of the chat window
	private void DoChatWindow(int hwnd)
	{
		// I have a bool to identify a minimized/closed chat window or the full thing
		// this button will "Close" the chat window.
		if( GUI.Button(new Rect(380, 0, 20, 17), "X") )
			m_bChatWindowOpen = false;

		// Name the chat input control
		GUI.SetNextControlName("ChatInput");
		m_ChatMessage = GUI.TextField(new Rect(0, 190, 400, 20), m_ChatMessage, 512);
		GUI.SetNextControlName("");
		
		// Show the last 11 chat messages
		// from the message log.
		int chaty = 165;
		int chatcount = 0;
		
		if( m_ChatMessages.Count > 0 )
		{
			for(int i = m_ChatMessages.Count; i > 0; i--)
			{
				GUI.Label (new Rect (5, chaty, 390, 20), (string)m_ChatMessages[i-1]);
				chaty-=15;
				chatcount++;
				if(chatcount > 10)
					break;
			}
		}
		
		// Now check for the enter key		
		if(GUI.GetNameOfFocusedControl() == "ChatInput")
		{
			if(Event.current.Equals(Event.KeyboardEvent("return")))
	    	{
				if(m_ChatMessage.Length > 0)
				{
					// Send the message to other clients
					SendChatMessage(m_pLocalClient);
					m_ChatMessage = "";
				}
		    }
		}
	}

Again, this code works just fine on Mac in Safari or Firefox, but not at home on my windows machine. Is this a known issue? Is there something wrong with my code?

Did you ever get this working? I’m having a similar problem with the enter key in a gui window
