I can't run it on my Windows 7 64bit Ultimate machine, so any time I need to modify screens I use one of my XP Professional machines. I'm contemplating "upgrading" (probably a clean install is necessary) one of my XP machines to Windows 7 32bit. Will FPW 2.6a run on it? If I do this I'll have to choose between the Home Premium and the Professional (or even Ultimate) editions. The Professional version supports running Windows XP programs in Windows XP mode. Would this be a benefit? My experience using my Windows 7 64bit Ultimate machine running in compatibility mode has not been positive. I did install an emulation download of Windows XP on the 64bit Windows 7 machine, but dislike having to use it and never do. Thank you for your comments.
