The option Open the attachment does nothing, no reaction, no disk usage no process starting, simply nothing happens. Does not matter if I try to open it from the link Open file prom the attachment page or if I try it from the handy menu or with keyboard shortcut. Simply absolutelly nothing happens. Displaying attachment as text or saving is functional without problems. It simply happens everytime. Tested on 3 instances with windows XP (one after clean install) and one instance fo windows 7 rc. It seems that is windows version independent. Associations in system is set up correctly, no other program has problem with openning files, no other mail program (sylpheed, thunderbird, windows live mail...) has a problem with it. I am using gpg4win standard and light, does not matter which instaler I choose, it shows me that I am using the version 3.7.2cvs15.
