Answer 1

It might be occurring due to browser and Flash security restrictions, the clipboard injection can ONLY occur when the user clicks on the invisible Flash movie. A simulated click event from JavaScript will not suffice as this would enable clipboard poisoning.

It has been mentioned as limitation of zclip plugin in its github repo. Please refer to github link for more details

And for clipboard poisoning please refer to this link

2. Easy to use and configure
