Hello Corinna,
Selon Corinna Vinschen <[EMAIL PROTECTED]>: > The cause is a limitation in newer Windows NT versions, which make sense. > Well, sort of.

That's amazing! I didn't expect to get a reply today. Even less a fix commited to CVS. If all bugs last only 51 minutes in Cygwin, this software will quickly become perfect! Thanks _a lot_ Corinna ! I'll try Cygwin snapshot tomorrow and let you know how it goes with the real stuff.
