Hi Pauline - I use CA on a number of different PCs, and the effects you describe are present, but can be cured. I create a folder called PLAY, which can then be made an exclusion within the CA programme. From the CA Scan Settings menu click Modify on the Real-time Scanner row, and Add the "PLAY" folder through the browse facility. When you accept new AVs they should still be loaded into a normal folder, subject to scanning, but can then be copied into the PLAY folder. Anything in that folder will not be scanned when launched, and the problem effects will dissappear. You will also notice that icon appearance is instant, rather than delayed as occurs in a scanned folder. Once running, the transitions are likely to be smoother, and any sound breaks should be cured. Hope this works for you. Alan
