Hey,<br><br>Thanks for the &quot;thead apply all bt&quot; tip, gets me a bit more info.<br><br>As it happens I fixed the bug that cause this thread by mistake, it was a deadlock in GUI code.<br><br>I&#39;ve looked into valgrind and helgrind, getting lots of output... don&#39;t really know how to use it yet.<br>
Tutorials and man will sort me out when I get time...<br><br>Thanks, -Harry<br>
