Hi Christian<br><br>The backtrace oft the crash says "OpenGL test failed". To better understand your crash we need some more info<br><br>* what graphics card do you use<br>* do you run NeuroDebian in a virtual box on Windows or Mac?<br><br>Additionally, you can download our latest deb packages from OpenWalnut.org ... They are not yet available In NeuroDebian (but will be soon :-) ).<br><br>Cheers<br>Sebastian<br><br>--------<br>This message was NOT sent with an iPad<br><br>Christian Stephan-Otto <cstephanotto@pssjd.org> schrieb:<br><br><div class="gmail_extra">Dear neurodebian community,</div><div class="gmail_extra"><br></div><div class="gmail_extra">I just installed OpenWalnut from the repository but it immediately crashes when I try to run it.
