wysota: This is not the problem because i have not modified my computer.
wysota and jpn: If i used upper letter dont work.
minimoog: Because I need to resize image.

I know whats the problem but I dont know how to correct it. The problem is that if i create an object at first (in this function initializeGL()) works fine, but if i create an object from a file after initializeGL() dont work.

I have read that renderPixmap run initializeGL, PaintGL and resizeGL, and thats the problem. I create an object out of this functions (reading from a file).

I wish i explain well.
