I can confirm this random "Extended features getting disabled" bug is still present under Adobe Reader 9.3.1.
The only known workaround is to keep opening the document till the error disappears.
Using Adobe Reader 9.3.1 for Linux.
I'd like to piggy-back on this thread. I am also having this issue and closing and reopening the document until the error message goes away is not a solution.
I'm using Acrobat Pro 9.2.0 for MAC and enabling extensions for Reader. The Reader version our company uses is Reader 9.1.3 for PC.
As in the original post, it's a single user that continues to have these issues. All the other people that touch these files have little/no problems with this. Tech Support has tried reinstalling Reader and it seemed to work for a few days and now the issue is back. Anyone have a clue on this?
Here's a screenshot of the error, which is also stated in the original post.
My company is having the exact same problem. We have had documents with no modifications, just stop allowing field filling. This is a very serious problem for us. Does anyone have a solution or patch yet?
It seems to be an issue with early Reader 9 versions and Windows XP
on the PC side, we had no issues with Windows 7 running Reader 9.1.3. Update to Reader 9.4.3 or preferably Reader X
. All this should clear out.
This was my fix, no guarantee it will work for everyone else.
I am having the same problem. When the form is emailed from a pc to a mac, the extended features are dropped. When the document is emailed from the mac back to the pc, it works fine.
Looks like a mac adobe reader issue for me.
