We’ve had some great feedback on the new Knowledge Tree filters introduced in the last release and I am very pleased that it has been so enthusiastically received. A comment we did get from a few people is they wanted the expand/collapse state of the filter pane to be retained across sessions, which is the main update in this release. Some folks also reported random crashes in V18.104.22.168 which turned out to be caused where Internet Explorer Version 6 was still being used. We have resolved this as well, however we would urge people who have yet to upgrade to IE7 or IE8 to do so as soon as possible, as there may well now be other problems related to IE6 that we are not aware of.
I have also updated the Knowledge Tree Filter to maintain independent settings for the Normal tree view and Folders Only tree view, fixed some bugs related to the new filter code and addressed some other recently reported issues.
