KBailey 0 Report post Posted October 25, 2018 I accidentally clicked the check box to not remind me again about 'closing all tabs' warning when clicking the main X in Nitro. How do I bring back this warning, as I have closed pdf's I'm viewing multiple times. Share this post Link to post Share on other sites
