Spanish post is correct but i think he made a little mistake in his link
his link is this
'C:\Program Files\Sports Interactive\Football Manager 2008\fm.exe" -small_screen -windowed'
but it should be the one below..please take note of the colen at the start and the end
"C:\Program Files\Sports Interactive\Football Manager 2008\fm.exe" -small_screen -windowed
copy my link into you shortcut and you should be able to start in non full mode.... |
