I have windows xp with adobe reader 8. When I try to open a pdf attachment file in my email it wants to go to my browser and won't open. Just get a warning messege. I want it to open in adobe reader. I can save it and then open it from my documents given on option when I right click. I do not get any options when I right click while it is still attached to the email. It started when I screwed up opening another pdf file in my email. An option box poped up with a chice between adobe or browser. I picked browser and then clicked the apply button. I have not been able to undo it. I can't find that option.
