I am considering purchasing Windows 7 but before I do, I have a few questions. First of all, I am using an old Dos genealogy program that I can't get an upgrade for. This company has gone out of business. I've tried other genealogy programs but none of them add up to this one. Now, I am using Windows XP Professional and this program works great under the compatibility mode of Windows 98/ME. If I installed Windows 7, would I still be able to use this program? Is there anyone out there using Windows 7 and still using their old Dos programs? How do you like Windows 7? Is it worth it? If you had it to do over, would you? Thanks for your time.
