Maybe you can gain some insight from the fltk README.mac file:
http://svn.easysw.com/public/fltk/fltk/tags/branch-1.1.9/README.mac

Also, what verdion of fltk are you using? reading the README.mac file
for version <=1.1.7 I see the following:

KNOWN MacFLTK BUGS

    The following FLTK things are not implemented or don't work
    at present:
       ....
	- OpenGL subwindow during window resize changes position

So maybe an fltk upgrade will solve this problem?
