I work at a large hospital IT shop and we recently pushed Reader 9. First we had the issue where we couldn't open .pdfs in the browser so we had everyone decheck "Display PDF in Browser" under preferences. This didn't solve the problem but just enabled a popup of the pdf external to the Browser.
We are also having an issue with once fillable forms no longer being fillable. If i uninstall 9 and revert to 8 I can editthem. However, they are not working in 9.
I am forced to use IE6 due to an applicaiton dependancy so I am guessing it could be an IE6 issue, thoughts?
