This question isn't directly related to Opus, but it has an interesting subject that relates to it...
The new explorer in Vista has, in most ways, been drastically improved. It actually asks you now if you want to skip ALL files you've already copied and things like that.
Something weird though, is that it doesn't seem to copy things in a consistent order. If you have files named "001, 002, 003..." it doesn't seem to copy them in the order that you have them selected like it normally would.
Is vista doing something like saving conflicts for the end of the job, if you've already got some copied, so that it gets whatever it can done, and then asks you about the conflicts at the end of the job? This kind of thing would make WAY too much sense for microsoft, and I kinda doubt they did something that smart...
BTW, that'd be pretty neat if you could have an option in DOpus to save all the conflicts that need your response for last, so that if you were doing a massive copy job or something, you could walk away for a day, and come back and not have to babysit the job. Either that, or the program would try to get those all for you right away and then start the job.
