I have windows vista home premium 32bit and when I make an ISO file it shows with the sheep icon, when I play the file no problem and all I do to stop the sheep showing the name of the file I just played was to 'eject' it by right clicking on the sheep icon. But here is the problem: If I want to erase that ISO file I can't, the program tells me it is being used by another program and can't be erased, I realise it is because the file has been mounted but the friggin 'mount/unmount' file commad isn't shown in the menu options when I right click on the virtual sheep on my C drive! So how can I unmount it?!!! My only option has been to restart the PC and then I am able to erase the file or play another. What a chore. It used to be shown on the menu options now the 'mount'unmount' commans if F---ing gone, even if I search the C drive program files its too confusing. Help/ email me etc. thanks.
