Dear All,
I have Just found the real problem: it was not SWMM5, but the default settings of WindowsXP. In fact, by default WindowsXP uses the "." as hours separator (Control Pannel-International options-Houre); i changed it in ":" and now everything is all right (even without manually change the *.inp file...).No bug! Sorry!
Greetings to all,
Camorani Giorgio
