Thanks for the reply Tom.
The MAC and the PC are both connected to the sever which is running the application.
On the PC, when I click on the 'View Document' button, the PC presents a dialog box which asks me if I want to save or open the file. This works great.
On the MAC, when I click on the 'View Document' button in the application, nothing happens if the stored file is a .pdf.
If the stored file is any other file, say a .txt file, the file is downloaded to my downloads then opened using viewer, this does not happen if the stored file is a .pdf.
I am currently running Version 4.0 build 1151
Hope this clarifies my problem.
