I'm using Adobe Acrobat Pro XI which is fully up to date. Over the last few days when trying to comment on scanned pdfs using the "more annotations" tab I get an error message ('adobe has stopped working please wait while we check for a solution....' etc) and eventually it shuts down.
I wondered if it was the scanned pdfs causing this, but I've checked with regular pdfs which I was able to open and comment on previously, and it is also shutting down shortly after I open the annotations panel.
Anyone heard of this problem? very frustrating as I have to mark a bunch of student exam answers by the end of the day which is impossible as I keep having to re-open the pdf and sometimes my notes are not saved.
