I have the following situation. I generated forms using Adobe Acrobat 9 Pro, checked the option "Choose Advanced > Extend Features In Adobe Reader" to make forms fillable and savable for Acrobat Reader users.
So far everything worked fine. User could open with Acrobat Reader, complete forms and save. However, when these files were re-opened to amend something or sent to others for amendment, the can not be saved again in altered form.
Anybody has a suggestions how to overcome? User are not all part of the same network and spread out all over the world.
