ID3DXSprite::Flush() Hanging

[pogrady]

Hello,

I'm wondering if somebody can see something that I am missing.

I have a font class that takes a struct with some information and renders the string to a specified location. It then clears the list after the call to end scene. The problem is that the call to Flush is hanging and i don't know why. It stops only after the second iteration.

Here is the code:

struct TextObject
{
	string mString;
	tagRECT mLocation;
	DWORD  mColor;
	DWORD  mFormat;
};


class cFont : public cRenderObject
{
public:

	 cFont();
	~cFont();

	//Intilaizes some default values.
	bool Intialize(LPDIRECT3DDEVICE9 Device);
	void Render(LPDIRECT3DDEVICE9 Device);
	//adds new text objects to the render list
	void AddTextObject(TextObject* NewText);


private:

	//the font object
	LPD3DXFONT   myFont;
	//the sprite object associated with the font object
	LPD3DXSPRITE mySprite;

	std::list<TextObject*> myStrings;


	void Print();
	
};
void cFont::Render(LPDIRECT3DDEVICE9 Device)
{	
	mySprite->Begin(D3DXSPRITE_ALPHABLEND);
	Print();
	
	HRESULT r = mySprite->Flush();
	if(FAILED(r))
		Print_Text("cFont: Failed to end scene.");
	r = mySprite->End();	
	
	myStrings.clear();	
};

void cFont::Print()
{
	list<TextObject*>::iterator itr;
		
	for(itr = myStrings.begin(); itr != myStrings.end(); itr++)
	{
		
		myFont->DrawTextA(mySprite, (*itr)->mString.c_str(), (*itr)->mString.size(), &(*itr)->mLocation, (*itr)->mFormat, (*itr)->mColor);
	}	
};

Even if I call ID3DXSprite::End() without calling flush, the program still hangs on End().

I also have an ID3DXMesh object that, when added, the cFont render() hangs, but when I remove the ID3DXMesh, the program runs normally.

If I comment out the cFont::Render() function and the ID3DXMesh object is included, the program loads and displays the Mesh normally.

Thanks for the help.
