I have a TAdvToolBarPager with the Clipboard, Font, Paragraph and Editing Toolbars included but there seems to be an issue with the TAdvRichEditorClipboardRibbonToolBar when selecting Bold, Italic, Underline, SubScript and SuperScript as the buttons remain unchecked! bsCheck is not getting set for some reason. It works ok on the Paragraph Toolbar with the Alignment Buttons.
Thanks for reporting.
We traced & fixed this issue. The next update will address this.
