Ok, I had a pretty strange thing happen in my program the other day.
I changed the way I constructed an object and this caused my program
to just hang.  Here are the two ways I constructed them...

//method one
//first i define some stuff up here...and then....
class myship
{
   int x, y;
   BITMAP* image;

   myship(int newX, int newY)
   {
      x = newX;
      y = newY;
      image = (BITMAP*)data[myship].dat;
   }
}

//method two  
class myship
{
   int x, y;
   BITMAP* image;

   myship(int newX, int newY) :
      x( newX ), y( newY ), image( (BITMAP*)data[myship].dat )
   { }
}

//////////////////////

Now the ONLY change in my source code that I make are these two 
constructors.  When I use method one, everything works fine, when
I use method 2, the program hangs, it seems to crash actually.

Does anyone know why this is?  It might help to know that the
graphics functions I am using are rotate_sprite() and blit().

Any help would be really appreciated.
