Logic would suggest that people would have noticed all the people who have reported experiencing it over the years too, but apparently it passes them by if it doesn't affect them, leading them to believe it's an extremely rare occurrence ;)
Definitely not 'awash with reports' though, which, considering the number of years and users involved, suggests a relatively rare occurrence to me. ;opYou're probably right about the coding style being the main contributory factor. Still, pretty weird all the same. :o)
