i have changed setting to acrobat reader default but everytime i click label to open I get a pop up box and it has a box that i check so "do this automatically for files like this from now on" and I checked that little box but it never goes away this pop-up comes up all the time

ok i closed browser cleared cache and it worked where it opened and went to print. It only worked one time as now its doing same thing as down loading .any suggestions?
