Hi SoCal App You will remember that I was unable to install the updates even after very briefly (and very much against my better judgement) suspending my AV protection. I suspect it was because I have quite a lot of other stuff which Adobe won't like because it may limit the opportunity to make a buck. Some of it is deliberately aimed at frustrating Adobe and to turn it off is like bending over and saying "Ok big boy, **** me" and I don't want to do that. I'd prefer to take my chances with the out-of-date plug-ins, I think.
Thanks for the link to Gnash but have you any opinion or even experience of it - first or second hand? They claim that it's now much more competent, totally honest and upfront - but they would say that, wouldn't they?
