Very, very long time user of yahoo mail. Multiple email accounts on multiple PCs. Recently, for several days now cannot open Adobe attachments on any of our PCs on any of our accounts. Tried newest version of Adobe reader, tried disabling security, tried different browsers - nothing works. Anyone else out there with this problem? If widespread could be very serious. At wit's end. Will soon be forced to use Gmail or MSFT after close to 15 years. Already forwarding some emails to Comcast - where we can view.
