Thanks for the post. I've had the same problem which I haven't been able to solve.
'Packet-writing' (the type you've described here) works a charm on my Win98se PC but on a friend's WinXP PC it suffers from the above symptoms. Both are using Easy CD Creator, though different versions - shouldn't be an issue, should it?
Anybody knows what's going on here?!
P.S. Joe, sorry for adding my 2 pennies worth. Don't mean to 'hijack' your thread : ) Just want to keep track of it so I too can be made aware of a solution when it becomes available! Regards, G
