Tame Acrobat Reader to avoid browser lockup

To avoid Acrobat Reader taking over your browser window (which sometimes locks up the browser):

• open Adobe Acrobat Reader from the Start > Programs menu
• then Edit
• Preferences
• choose Options (or Internet in 6.x)
• uncheck the box for “Display PDF in Browser” (make it blank).

After that, you’ll get a file download box when you access a PDF file, and Acrobat Reader starts automatically when you choose Open.
