</div></div>Oops, missed that. I do see that you have parented the drawer to the<br>
KCategorizedView though.<br>
As a wild guess - try not parenting the KCategoryDrawer instances to<br>
their respective views - I can't recall exactly but there might have<br>
been a problem with doing that as otherwise I wouldn't have deleted it<br>
by hand in the IconMode code in System Settings.<br>
