Comodo, Avira, Eset and Baidu are detecting something fishy about it. Perhaps the installer was detected as a suspisious file by the AV you are using. Thanks Gabriel Fernandez and GOTD for this fantastic Giveaway. I truly will give it a go, can't be that difficult?:) BTW - having KB Piano2 sent to my taskbar and writing this text - I can hear sounds as I'm writing. The song doesn't sound the same (I really wanted to start with the simplest form and record it before moving to something more elaborate and fun) I wrote down that tune when testing (my real piano is so out of tune at the moment I was really glad to hear each note as it should be, lol) - it goes as follows: GGEAG GGEAG GGE GGE GFEDC. I cannot get it back (help!:) Piano keyboard appears for practicing but single notes I could here before can only be pressed on keyboard-keyboard (same default option as before) but they are not single any more. When I first opened it and tried to play a simple tune I so often sing to my granddaughter (our song:) on piano keyboard (which appears when pressing 'practice') I was able to hear each single and simple notes which make this uncomplicated piece - as underneath that 'piano keyboard' I could see 'test' option. Hi, Wonderful Software!:) Loads to learn thou.
