>Just got our new Vista system, and started testing some of our legacy Foxpro 2.6 applications. This is the first incompatibility we detected:
>
>The RUN Command does not SEE any files!
>
>For example when you run
>RUN dir/p
>
>It does not show the file names.
>
>If you run RUN COPY *.DBF c:\trash
>It responds with "File does not exist..."
>
>So, if you are using the RUN command to copy files w/Wild Card name/extension, you'll have problem (Since Foxpro2 does not support wild card in it's COPY FILE command).
>
>I even right clicked on all the Fox*.exe files and set their compatibility to Windows XP (since it works just fine under XP).
>
>Any ideas or suggestions will be appreciated.
