Maybe this is a personal problem but I do this all the time and It frustrates me every time.
Edit an icon go to hit OK a little too fast and catch the cancel by mistake, all my hard work GONE. Yes this is only a loss of a few minutes but time is money. Do this 1 out of 50 times I edit an icon, ant it happens a few times a week.
Can we move the cancel button away from the OK or can we add an optional confirm on unsaved changes to the icon so I dont loose my work every time I make this mistake.
National Instruments will not be implementing this idea.
