Help. Trying to get Buddy API to open a file in project burnedto CD-ROM

Anyone have an idea for this.

I am working on OS X, Director MX, Buddy API version 1.4

I have built a Mac Classic Application, that at one point a button has to
open a PDF file, in a subdirectory, of the Director Projector. Nothing
fancy,

on mouseUP
baOpenFile( "@:FORM:FORM.PDF", "" )
end

That is the code.

Now here is the weird part... I built the project and it works fine when on
the hard drive [opening the file and everything]. But when I burn the
project to a CD-ROM, that part of the projector refuses to work. In fact
nothing happens, no error codes or anything. The button clicks and that is
it.

In short Buddy API code in project on...
Hard Drive = Works Fine
CD-ROM = does nothing

Anyone have any suggestions?
