I have a few users with this issue.
When opening a new Microsoft Word 2013 document (blank doc) the keyboard will not type, only give the beeping as though you're pressing the wrong key at a dialog, until you either right click, open a new document or activate sticky keys.
I have tried searching for possible solutions, have tried a reimage of the machine (not every machine is experiencing this, but over 300 machines have this image), have tried disabling Bluetooth add ins, and repairing Office 2013. Blew away the profile on the machine and the issue remains.
Has anyone else experienced this? Anyone have a solution?
