not a real bug, anyway in the statusbar, a double click on the box USS opens the messages window.
I solved in this way, if someone interested to fix it or suggest other way

@mulestatusbarctrl.h

enum EStatusBarPane
{
	SBarLog = 0,
	SBarUsers,
	SBarUpDown,
	SBarConnected,
	SBarChatMsg,    
	//-> ADD    
	SBarUSS
	//<-
};

@mulestatusbarctrl.cpp

switch (iPane)
	{
     	[...]

		case SBarChatMsg:
			theApp.emuledlg->SetActiveDialog(theApp.emuledlg->chatwnd);
			break;
		//-> ADD
		case SBarUSS:	    	
			theApp.emuledlg->ShowPreferences(IDD_PPG_TWEAKS);	    	
			break;
		//<-
	}

@emuledlg.cpp

void CemuleDlg::ShowPing()

{
    if (IsWindowVisible())
	{
		[....]
        }
        statusbar->SetText(buffer, SBarUSS, 0); //-> CHANGE    	
     	
    }
}


void CemuleDlg::SetStatusBarPartsSize()

{
	CRect rect;
	statusbar->GetClientRect(&rect);
	int ussShift = 0;
    
	if(thePrefs.IsDynUpEnabled())
	{
    	
        if (thePrefs.IsDynUpUseMillisecondPingTolerance())
     	
            ussShift = 68;  //->CHANGE
        else
            ussShift = 113; //->CHANGE
    	
	}
    
	int aiWidths[6] =  //->CHANGE
	{ 
		rect.right - 675 - ussShift,
		rect.right - 440 - ussShift,
		rect.right - 250 - ussShift,
		rect.right -  25 - ussShift, 
		rect.right - ussShift,  //-> ADD
		-1
		//<-
	};
	statusbar->SetParts(_countof(aiWidths), aiWidths);
}

This issue is still present on 0.50b.

Finally fixed in SVN.
