I have a fillable PDF form designed in Livecycle designer and it is reader extended. When I fill that form on MAC it let me fill and save the form as many times as I like. Everytime I make any change I just click the save button it saves changes in the same form. BUT is is behaving differently on Windows. After filling the form out when I click on save button it opens up "Save as " dialogue box to save a new copy with those changes. I have Adobe reader XI and Adobe Acrobat XI installed on windows. I know I can do that with Acrobat but I want that in reader for users who dont have acrobat.
