John,
  i appreciate the suggestion but there are various technical reasons
not to do this, including this must be done for other smaller drawing
areas.  this is one of the reasons why i insist it be done at loading a
file.  additionally, this would make my code look not messy in one place
but like i barfed on the whole project.  this is for a portfolio so it
cant look as such.

Everyone,
  as i pointed out before i had tried to manually execute the callback
but the memory was not allocated for the window.  im wondering if there
is a way to allocate the memory and tell the program it has been
allocated so that it wont do it again.  however, maybe it just checks if
it's NULL and then allocates... who knows.  

i have a screen shot of debug data of two instances of my application
running with info pointed out: http://adaptivetime.com/debug_shot.png
