That man never said what you talked about. He just said "don't use OS version checks at your applications for compatibility issues". I'm not a OS expert but I think so they just cutted it's thorns... :)

>The 6.1 thing is only for compatibility issue. Some software only check the first digit when verifying the OS version. So if they use something like

IF VERSION() = 5 OR VERSION() = 6
>   *-- Proceed
>ELSE
>   *-- Wrong OS
>ENDIF

the software will still run under Windows 7. If they changed the version to 7.0, the code above would have broken.

>>That's interesting. I learned that from Microsoft Turkey at a seminar; Vista is Windows 6.0 and W7 is just Windows 6.1 actually. However if I'm not wrong there is a new bug at VFP SP2 from SP1.
