Having trouble saving a PDF?
Some free versions of Acrobat Reader do not allow Save. You have to save the PDF from the IJBS page you downloaded it from. PC users: Right-click on the Download link and choose the option that says "Save Link As" or "Save Target Asac users should hold the mouse button down on the link to get these same options.
If you still have question, please send to mail@ijbs.org
