Hello,
I have downloaded and compiled Code::Blocks from the svn repository
$ svn checkout 
http://svn.berlios.de/svnroot/repos/codeblocks/trunkI created a new wxWidgets 2.6 (and 2.8 ) project with the name "test". The project was created Ok but the wizard put a "." into class name instead of "_".  The "." makes the generated code erroneous. 
Selected options were:
Preferred GUI builder: None 
Application type: Frame Type 
And "Use default wxWidgets configuration". 
The wizard script is /usr/local/share/codeblocks/templates/wizard/wxwidgets/wizard.script
wxWizard project "test":
/***************************************************************
 * Name:      test.cbpMain.h
 * Purpose:   Defines Application Frame
 * Author:     ()
 * Created:   2007-05-31
 * Copyright:  ()
 * License:   
 **************************************************************/
#ifndef TEST.CBPMAIN_H
#define TEST.CBPMAIN_H
#include "test.cbpApp.h"
class test.cbpFrame: public wxFrame
{
	public:
		test.cbpFrame(wxFrame *frame, const wxString& title);
		~test.cbpFrame();
	private:
		enum
		{
			idMenuQuit = 1000,
			idMenuAbout
		};
		void OnClose(wxCloseEvent& event);
		void OnQuit(wxCommandEvent& event);
		void OnAbout(wxCommandEvent& event);
		DECLARE_EVENT_TABLE()
};
#endif // test.cbpMAIN_H
My operating system is Ubuntu 7.04 Linux.
