 Hi John,

 I just built GRASS 6.3.0 on Windows Vista (Home Premium) through the
 MSYS/MinGW environment, exactly as I built it on XP. I made only few
 tests, but both r.patch and v.patch worked fine for me.

 This said, I don't think that it depends on the new build: I think that
 the problem lies on the UAC system, because it forbids third party apps to
 write outside the "Program Files" and "Users/Account Name" folders,
 specially if the destination folder is directly in the unit root (such as
 C:\), and sometimes even if the user gives the permission after the UAC
 alert prompt message;

 So, disable the UAC (see http://www.vista4beginners.com/How-to-disable-
 UAC) and then try r.patch with the current WinGRASS binary release (still
 built on XP);
 Let me know if it works :-)

 Marco
