you know RC is close when you start seeing more and more winmain builds leak. This make 3 leaks in less than 2 weeks (well 2 if you take into account the actual builds not the arch types)
Yep, it seems things are moving at a fast pace now, quite a few changes in 7057. EDIT: have you tried with a normally installed copy of the latest version......?? I would suggest doing that.
as i say, have you tried with the latest normal version of 7zip??? That is installed normally, not a portable version.??
