Try the save button.
I have a similar problem. I can't save files downloaded from e-journals. worked fine before this version. I've heard of small bugs in version changes, but this is a critical loss of functionality. I've tried reinstalling, but that doesn't work either. guess I'll have to work with the older version until the adobe team learns how to program again.
I have the same problem with v9.1.3. If I click the Save button nothing happens.
This is a problem with some of my statements. Others save correctly.
Sometimes if I righclick the link to the statement in my browser (IE8/Win7) the file will be saved as a PDF, but a left click will open the PDS in the browser and the Save button does not work.
So far I only see this with various statements. Opening other PDF files in the browser, such as user guides, manuals and others works all the time.
