Because from the DOS prompt your program is invoked as ".\OurApp.exe", and
from Explorer it's invoked with a full path (i.e.,
"C:\OurAppFolder\OurApp.exe").  Cygwin translates the current directory
into a POSIX path.  In the first case, the current directory is ".\",
which in POSIX is "./".  Now, since Windows understands mixed paths, it
interprets this correctly, so your program works.  In the second case, the
path becomes what you see in the error message above, which is not
understood by Windows.

I'm not sure how to avoid path translation.  You could try invoking wish
as
   execlp( "wish", "wish", "OurScript.tcl" , ...);
instead...
