Internally Hauptwerk uses the Qt multi-platform library for its graphical user interface. The left-hand object list boxes on the settings screens, and the rank list on the voicing screen, are QtTreeWidget controls. I've just checked, and you're right that evidently on Windows Ctrl+Up and Ctrl+Down key combinations don't appear to do anything with those controls (although other standard Windows controls do work for them, including Ctrl+A, Shift+Up, Shift+Down for multi-selection). I don't know whether that's intentional on the part of Qt's makers for some reason, or simply an oversight. If the latter, hopefully a later version of Qt will add support for those particular key combinations. Anyway, I'll log it in our database for now, just so that we have a record of it.

The release notice lists non-trivial known issues and bugs that are likely to be of relevance to users. We did also post a temporary list on the forum ( viewtopic.php?f=10&t=17970 ) for v5.0.0 issues/bugs prior to v5.0.1's release. (The forthcoming v6.0.2 will address additional things found since v6.0.1.)
Aside from that, to my knowledge there hasn't actually been a separate known bugs page on the main website for quite a few years. Can I ask where you found that broken link? If so, I'll pass that on to the people that maintain the website to get that addressed. Thanks.
