Opengl Step into

Noticed when I run several Fortran routines that produce calls to another, if I use the 'step into' debug function, it enters into and steps through the called routine. However, if I do this with Opengl calls, it does not enter into the called routine? Is this normal? Sid Kraft

Whether you step into OpenGL routines, other library routines or your own routines, if those routines do not have their debug information compiled into them EXE or DLL, you will not be able to follow the execution of the program in those routines. Yes, that is normal.
