I also would like to change the default save to location. When saving multiple documents the previous Adobe Reader would use the save-as location of the first document saved which decreased the amount of clicking around to find the same location for the 2nd, 3rd, and so on documents.
We have also experienced this same issue and would like to know how to specify a default folder location. Please
let me know if you receive an answer to this inquiry.
1-go to "edit", select Preferences.
2-select from the left pane: Security (enhanced)
3-click on "add folder path" button just below the big white box
4-pick a folder of your choice and click "ok". (your selected folder path will appear in that white box above the "add folder path" button in step 3)
5-if you want to add additional folders, just repeat steps 3 & 4
6-once you are done, click "ok" on the preferences screen and click "ok" again to accept the changes.
Yes, it seems illogical, but it worked.
I tested by closing the Reader (X), then surfed the web and did what Neher5 was explaining he/she wanted to do just after opening a pdf from a website and lo-and-behold, it worked!. No more "save to temp folder" issues.
Hope this helps.
