------------------ Additional Follow-up Comments ----------------------------
It's not grey in grey, but not painted at all. The reason is a interger 
overflow in Rectangle.cs. This is caused by the following line (appears two 
times in TextBox.DrawText):

   ControlPaint.DrawStringDisabled(g, lineText, font, BackColor, new 
Rectangle(x, y, int.MaxValue, int.MaxValue), StringFormat.GenericDefault);

This causes problems in Rectangle.IntersectsWidth()

public bool IntersectsWith(Rectangle rect)
{
        return (rect.x < (x + width) &&
                (rect.x + rect.width) >= x &&
                rect.y < (y + height) &&
                (rect.y + rect.height) >= y);
}


I don't know if this should be patched in Rectangle.cs or in TextBox.cs; maybe 
both.

Summary:  TextBox shows Text in "grey on grey" when not enabled

Original Submission:  The text in a TextBox should be readable even if the 
TextBox is not enabled. Currently, the textbox turns grey and the text is not 
visible.
