Hello, The Yab interpreter by Jan Bungeroth has a screenshot function. On netbooks, this function seems to hang when it calls: BScreen.WaitForRetrace() (This is called without the timeout parameter). Is this a netbook video-driver bug? Also, as a work-around, would it be safe to comment this line out, as doing so seems avoid the hang and it seems to work normally thereafter (and would this affect using the screenshot function on other non-netbook machines)? Thanks, hey68you
