He asked whether I have anti-virus installed, and whether I have looked at the "BLODA list". BLODA is the Big List Of Dodgy Apps, apparently from http://cygwin.com/faq/faq.using.html#faq.using.bloda 44. What applications have been found to interfere with Cygwin? From time to time, people have reported strange failures and problems in Cygwin and Cygwin packages that seem to have no rational explanation .... Unfortunately, "Norton/McAfee/Symantec antivirus or antispyware" is the second item listed. This is a work machine. IT installed Symantec Endpoint Protection on it and locked down absolutely every setting whatsoever (except for how long to keep local logs). I really doubt that they'd unlock anything for me, especially because I'm brand new and we don't do very much on Windows. Unless someone has another suggestion, maybe I just have to assume I'm SOL. -- Tim McDaniel, tmcd AT panix DOT com -- 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
