Chuck, do you need a > hand with going through them? Oh, riiiiight. The problem is this: since the win32 CWD is *always* bogus, it is possible that other win32 functions will croak, not just CreateProcess. So, there are a number of native win32 calls in the cygutils tools, like: cygstart: CreateProcess, among others lpr: ...many... putclip/getclip: GetClipboardData, SetClipboardData, etc Now, I haven't tested each of these tools exhaustively under cygwin-1.7.6, so I'm not sure the bogus win32 cwd affects them (except obviously cygstart). But...by their very nature many of these tools use the native w32api. So...each should probably take care to set the win32 cwd if at all possible. Yeah, patches would be great. -- Chuck -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
