MarkSalas, I'm bummed to hear that. Was hoping the upgrade would fix it across the board and was just about to push for a PRO Upgrade across the company, but apparently that isn't going to fix the problem definitively based on your findings.
brogers_1, you said that you found the associated bug and are adding this info into. I'm not sure what that means.
FYI, I read, and had my users try, right clicking on the previous version and viola, they are able to open the docs that way. This is our workaround for them for the moment until we hear back from Adobe on this issue and how to resolve it.
Thanks
