I downloaded the Disk Director demo which seemed to install fine. Clicking the OS Selector icon brings up an error message and the OSS closes down. The same thing happens if I try to access OSS from the DD interface. This app seems to do what I want, if it will only work properly. Are there similar problems with the paid-for version? I would like reassurance on this please as I need the functions of the Disk Director package. Thanks John PS I have True Image and that works OK.
