I saw the ticket earlier but now I can't find it anymore, I assume it is closed? This brings up some questions (I'm new to managed projects):<br><br>1. Where can I find closed tickets? (e.g., I can't see the "work around solution" if I can't find the ticket.)<br>
<br>2. If I am using the pre-built boxturtle install of ROS, how do I get updates of this sort? Do i svn just the packages or files I know are updated...?<br><br>Thanks,<br>Adam<br><br><br clear="all">Adam Leeper<br>Stanford University<br>
