I use Reader in a corporate environment and of course, at home.
This morning here at work I was prompted to install the latest and greates upgrade to what I presume is the free version or Reader X.
It suggested re-booting after installatin and I complied.
Now I open pdf's that 2 years ago would open in a heartbeat and I could literally fly through to find the informaiton I need. Now they open horribly slow and browsing through them is like watching spagetti sauce run down a wall ...at least for the first couple of minutes ...after which it appears all the indexing is done (for the 200th time on that document) and it finally starts to work.
This is a corporate environment and this increasingly poor performance is costing corporations a lot of money. If I as one user, spend 10 extra minutes per day due to this ...can you imagine the overall cost to corporations globally?? This is nuts Adobe. You are eroding the profit margins of the very corporations that facilitate your existence. Please go back to the drawing board. This isn't new. Each and every 'upgrade' since you included the indexing feature (or made it obvious) ...has resulted in slower loads.
