- Toolbar Spell Check reports "Spell Check Complete." without checking anything when the first paragraph is clean
- Options.ToolbarIconSize has no effect - toolbar icons are always the medium 18 DIU tier
- Spell check dialog can never show "Add to dictionary" - WPF defaults the user dictionary off while WinForms defaults it on
- Inline spell check: changing the misspelled-word marker style at runtime does not restyle words already flagged
- Shipped dialog labels rendered in all capitals (Style Builder, table, image, hyperlink, find, YouTube)
