We are facing an intermittent crash in Adobe Reader (both 8 and 9). This happens when the user is working with an Adobe Livecycle Designer Form. As enclosed the crash happens in uxtheme.dll which is a windows themes component. Since it is intermittent and not happening for all users, we are unsure as to where the problem maybe. After the crash the user is able to re-open the same PDF and do the same thing they were doing earlier.
