</div>One thing I would recommend is running valgrind on fluxus to check for<br>
hidden memory problems, especially for the fragile editor code.<br>
<br></blockquote><div><br></div><div>Ok, I ran it according to the quick-check guidelines and it quit on it's own before the Fluxus screen appeared. That doesn't bode well. Oddly the last issue (the cause of me not getting into Fluxus?) is actually a NVidea issue. I'm pasting the result below, some issues look familiar others make little sense at all to me. This is based on my binary which is exactly at the state of the redacted branch currently in Git. I don't think I tweaked more.</div>
