Hi my Amiga 600 is usually brilliant but I have a problem which I probably caused myself ,but when I try to boot up using 3.9 os nothing happens until I press the ctrl A A buttons and then it boots straight away and runs like a dream ,I am sure I must have altered some thing but I am not sure where to start and don't want to mess anything else up lol I have installed actune and was wondering if I have changed any thing in the start up ,but after saying that I installed actune a while ago and all has been well,best wishes Brian.
