--- Comment #8 from Christian König deathsimple@vodafone.de --- Oh, yeah you're right got that wrong as well.
But what I hoped to have checked as well is that it sounded like this copy command worked correctly in 90% of all cases and only in a minority just locked up.
Is that correct? Or in other words what makes this special case lock up? Does it work for other resolutions? etc...
