Nope, it doesn't happen! which is incredibly good news!

Hi Vincent,<br>
<div class="im"><br>
&lt;&lt; So.. could it be Rob&#39;s outliner enhancements then ??? &gt;&gt;<br>
<br>
</div>That&#39;s certainly possible, but I think it unlikely.  To the best of my \
knowledge, Jose only began using the branch with the expanded outliner and other \
tools yesterday whereas the problem  has also been seen in  LyX 1.6.6.1 and the main \
trunk.<br>


<br>
With that said, I think that we should be very careful about drawing conclusions \
about the SVN version of LyX from the LyX-Outline branch. The outline version has a \
lot of changes and the code is not particularly optimized (though I am working on \
cleaning it up).  I do find it interesting that turning off the Outline pane resolves \
the problems.<br>


<br>
Out of curiosity, do you notice the performance lags when using the expanded \
outline/corkboard widget?  If not, that would provide an important clue as to where \
the bottleneck is happening.  (My own gut says it has something to do with QTreeView \
on 64 bit systems.  I remember reading something about that on a forum a while \
back.)<br>


<br>
Cheers,<br>
