What do you mean by frozen?  Does none of the UI respond, or just the 3D window?  Can you provide a backtrace?<br><br>Josh<br><br><div class="gmail_quote">On Mon, May 31, 2010 at 12:34 AM, Ander Ansuategui <span dir="ltr">&lt;<a href="mailto:aansuategui@tekniker.es">aansuategui@tekniker.es</a>&gt;</span> wrote:<br>

<p class="MsoNormal">Hi all,</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">After reading the navigation tutorials I have successfully
configured the navigation stack in order to use it with our Segway RMP 200
robot. However, I have found some problems using rviz with the navigation stack.
</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">When I start up rviz for the first time, everything works fine
until I send a nav goal. Then, the robot starts moving, but the visualization freezes.
The underlying navigation stack works well, but rviz stays frozen until I rerun
it. Once I close the rviz window and open it again, it works again, until
another nav goal is sent.</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">I am running it on a DELL Latitude E6500 laptop (with an
Intel Centrino2 VPro processor and Intel GMA X4500 HD graphics card) under
Ubuntu 9.10. Any help is appreciated.</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">Thanks,</p>
