where Index_Tunes HL.pdf is the name of the file to open. As I say, this executes beautifully. However, it is on clicking the "Previous View" button that now there are two open files. As the application I am working on could involve extensive moving from file to file, leaving these files open is very messy and basically unacceptable to users. I thought possibly reversing the sequence of these two commands might change the result, but they behave identically.
I can't seem to find any preference that will change this behavior. Is there something I am missing that might help me correct this. Thanks.
