Hi Jim.... My CT 9.?? is at least 6 years out-of-date and so is the old DOS computer. Is CT for Windows available for download? If so, where? And also, if available, which versions of Windows will it run on? I'm using WIN 7 now but think I still have a usable old laptop with XP. Thanks much for any info you can provide. 73, Dick Ehrhorn W4ETO
