For now and many years WampServer works only with 80 port (http://localhost:80) and this is very painful.
If I will change the httpd.conf it starts work with other port, but not WampServer GUI (system tray context menu).
Every time I click any item from menu it targets me to some http://localhost/...... adress.
And it is silly enough.
I tried many things and hacks but it has no remedy.
