One of our staff has recurring issues with PDF print, view, save. These issue are temporarily resolved by re-installing the Reader from the Adobe website. No error messages are displayed - the functions just cease to work. In the most recent iteration of the issue a document attached to an email could be saved (right mouse click, save as) within the email program but not within the Reader itself.
It appears that Reader is getting corrupted - but by what? This individual does a lot of downloading of web published PDFs - a possible source but one I can't confirm.
Information on a permanent resolution or known cause would be greatly appreciated.
