Tech Note: Windows User - Deselecting the "Display in Browser" feature will allow you to open PDF's outside the browser in Netscape, FireFox, Mozilla, and Opera to name a few, but may not work for some users using Microsoft Internet Explorer (MSIE).

Some IE users have tried to deselect the "Display in Browser" feature and when they tried to open a PDF using MSIE, a second window would open and only show a blank white screen with a small image (image has a white background and includes a little red square, green circle and blue triangle inside it) in the top left corner and nothing else happens.

This is because MSIE uses the Acrobat Control for ActiveX to to display PDF documents. Netscape and other compatible browsers use the nppdf32.dll in the plug-in folder to display PDF documents. If this happens when you only deselect the Display in Browser" feature, try deselecting ALL four web broswer options and close both your IE browser and Acrobat Reader. Now see if this works... You can also try upgrading to the latest version of Acrobat Reader.
