I'm back again, tried IE as the default browser as suggested by others who had success with pdf downloads using 9.3.3 However....a warning to all, IE cannot be the default browser on 64 bit systems. All you get are poor internet pages with awkward presentations and lacking background. So until Adobe and Google can come up with a fix I may be hosed. Time to dust off my old laptop.
Doesn't MSIE have a setting to open websites in compatibility mode?
It is worth a try but does not solve the initial problem with the code conflict
when Adobe 9.3.3 was updated onto systems using Chrome.
