You can detach it from the shell.
try
Code:
wine MiniLogin.exe > /tmp/Minilogin.log &
Minilogin is now working in the background and its output will be written into /tmp/Minilogin.log. I'll write an propper init script as soon as I have time.
You could also use the command nohup
Code:
nohup wine MiniLogin.exe
downside is that the output is always going to nohup.out.
