--- Comment #4 from Dan Kegel dank@kegel.com 2009-08-08 00:07:05 --- Created an attachment (id=22895) --> (http://bugs.winehq.org/attachment.cgi?id=22895) +advapi,+relay,+process,+file,+ntdll of creation of the .rsp file
Looks like an security api problem? Attaching a log that shows some of the ACL futzing that happens as the file is being opened.
