mysterious behavior of wxDC in my program

[Christopher Bruno]

Here is what I am doing,

for class viewer (the canvas) class:

void Viewer:: OnPaint ( wxPaintEvent & event) {

      wxBufferedPaintDC dc(this)

      std::vector<ImageWrapper>::iterator iter

     for(iter =3D images.begin(); iter < images.end(); iter++) {

         dc.DrawBitmap((*iter).GetImage(), (*iter).GetX(), (*iter).GetY(),
true);
    }

}

it works fine for < 10-15 images in the vector, but after that it causes the
program to be unable to draw bitmaps, including the window, and bitmaps on
other windows. My machine has 2 GB of RAM - so its not a system probem

im new to wxWidgets (under a year of exp) -. anyone have any idea?
