I just installed WB6.2 on my machine running Server 2008 (I didn't have any version of WB on it before) and it appears that it has broken the Help feature. When I attempt to start Help from the start menu or from any links, Taskbar simply freezes for 30-40 seconds or so and no help system is loaded when it frees up again.
Hopefully this can be sorted out, as it is a pretty big drawback if this applies to everyone and not only myself.
