Copy/Move replace "Newer Only"

Oddly when I choose this option WinSCP the newest 4.2.3 beta the program freezes for about 5 minutes per file, but the system CPU doesn't spike 100%. I'm using Windows XP.

Peace out,
Paul

Did you get my email?

I have noticed the same behaviour with copy/move option "Not to all" and after click on Cancel button in the Confirm window also.
