Bug #3612: windows: unable to run path with spaces on it anymore. http://redmine.ruby-lang.org/issues/show/3612 Author: Roger Pack Status: Open, Priority: Normal ruby -v: ruby 1.9.3dev (2010-07-19 trunk 28684) [i386-mingw32] With 1.8.6 and 1.9.1, this worked: IO.popen("c:\\Program Files\\Internet Explorer\\iexplore") I assume it's a bug that it not work anymore, but am actually ok either way since...it's a bit surprising to *not* need quotes, since windows does on the command line. Let me know either way (if it is expected or not). This behavior is also present in 1.9.2 branch. Thanks. -r ---------------------------------------- http://redmine.ruby-lang.org
