I know of multiple Infor Syteline ERP users that are having similar issues to the SAP users who have already posted on this thread. I have tested the disabling of the Enhanced security and it did NOT fix our issues, at least in our environment. However our issue is identical to others: PDFs are previewed using the plug-in inside the ERP client, and on close it hangs for 10+ seconds (sometimes showing a 'Not Responding') and then finally closes. This is a huge issue and I know it is affecting hundreds if not thousands of users for that software package. I can confirm that DC build 20042 works correctly, yet 53 and 56 cause these errant crashes. When will Adobe be releasing a fix??
