Not necessary Cetin. Take a look at Vista and VFP. VFP run on Vista, but it have some repainting problem. Some window doesn't get repainted when they were hided by another window and the combobox dropout have a hilighting problem. Sure there is some workaround given by other users, but there just patch. What kind of compatibility problems will VFP have with Windows 2016? Will it be only cosmetic? Are you ready to take a chance with it?

>Producing incompatible versions would mean those windows versions wouldn't support any win32 application, not just VFP.
