In default style the threads widget alwasy shows scrollbars. Thsi was not the case in WS 2.5 but is an issue in 2.6
This can be fixed fairly simply by editing template wf_threads.css and changing Code: .WidgetFramework_WidgetRenderer_Threads .discussionList { overflow: scroll; width: 100%: } .WidgetFramework_WidgetRenderer_Threads .DiscussionList { min-width: 450px; width: 100%; } to just Code: .WidgetFramework_WidgetRenderer_Threads .DiscussionList { width: 100%; } Same thing was happening on older 2.6.0-dev releases too and that's how I fixed it then.
