Protected Mode causing slow opens Hi,I have Windows 64 bit and Acrobat Reader.Acrobat Reader hangs for an extended time when opening (even just the app, not double clicking a PDF) with 'Not Responding' with Protected Mode turned on (off it works fine)Its very frustrating when you need to open several files just to check a small detail.Have googled, but found nothing concrete, seems a lot of folk suffer with this issue - a short mention is made of 'delete temp folder', - but without any details, but am not sure where that is located, is that also related to 'autosave' ?Some suggestion of Network Folders made, could the App be trying to access one of those folders - which might be offline, with a temp autosave version ??? Bit stuck, any ideas ?? wasting a lot of the day on this.
