I just tested ARGO & QRS 4.02 using the latest Wine version 1.1.10 in Xubuntu 8.10 and both programs ran just fine. I just can't see a need to run a Windoze operating system now. Mini Ring Core Calculator runs in Wine as does Elsie, ExpressPCB & ExpressSCH. I haven't tested any other software yet but will be doing so soon. Mike WE0H /16
