All is marked when None should be selected.

Popups (ImageMiniToolBar and SelectionMiniToolBar) stay on most top (act as if "Always on Top" is set to them) even if they had lost focus. 

Workaround: Attach to LostFocus or LostKeyboardFocus events and hide the toolbar in the handler:
this.radRichTextBox.LostFocus += (sender, e) =>
{
    this.radRichTextBox.SelectionMiniToolBar.Hide();
    this.radRichTextBox.ImageMiniToolBar.Hide();
};

When the tabbed document becomes a dockable window the ContextMenu Icons are no longer visible.

In Word, default tab stops are not present in Paragraph's hanging indent. This leads to difference in the length of the Tab symbol in Word and RadRichTextBox, in cases when hanging is bigger than the default tab stop width.

When TextOptions.TextFormattingMode="Display" is set on RadRichTextBox, incorrect Measuring causes TextBlocks to not visualize correctly.

"Based on style" combobox is not filled with all linked and paragraph styles in the following cases:
- "Modify style" dialog doesn't display the possible "based on" styles in the combobox when editing linked styles. 
- "Create new style from formatting" dialog doesn't display the possible "based on" styles in the combo box during creation of new linked style.

Steps to reproduce:

Variant 1:
- Click Home -> Styles -> Change Styles in the ribbon UI.
- Expand the the drop down of Heading 1 button and click 'Modify'
Expected: 'Style based on' combobox contains all paragraph and linked styles.
Actual: 'Style based on' combobox is empty.
-------------------
Variant 2:
- Click Home -> Styles -> Change Styles in the ribbon UI.
- Click 'New' button.
- Choose 'Style type:' Linked in the combobox.
Expected: 'Style based on' combobox contains all paragraph and linked styles.
Actual: 'Style based on' combobox is empty.

This results in prompt to save the changes when closing the file.

The fix is available in our latest LIB(v. 2014.3.1222).

When a table is preceded by several paragraphs last of which is empty, selecting more than one of those paragraphs and the table excludes the empty paragraph from the selection. 

Steps to reproduce:
- Add paragraph with text, followed by empty paragraph, followed by table 2x2.
- Select from the beginning of the document to the last table cell (Note that the paragraph after the table is not included in the selection)
- Copy the content and paste it in the document below.
- The empty paragraph is not present in the pasted content, as it is excluded from the selection.

Performance of scrolling and editing is diminished when Track changes are enabled.  Issue seems to be related to RevisionsToolTipLayer and occurs when more than a couple of paragraphs are inserted in the same revision.

Workaround: remove the UI layer responsible for tooltips of revisions.

    [CustomUILayersBuilder]
    public class CustomLayersBuilder : UILayersBuilder
    {
        protected override void BuildUILayersOverride(IUILayerContainer uiLayerContainer)
        {
            uiLayerContainer.UILayers.Remove(DefaultUILayers.ToolTipLayer);
        }
    }

Text containing mixed Right-to-Left and Left-to-Right parts are visualized incorrectly - some of the punctuation marks swap their places.

Partial workaround: Use RadRichTextBox's TextRenderingMode = TextBlockWithPropertyCaching. This mode also has problems, but it works in some cases.

In RadRichTextBox, when i export pdf in memorystream Footers are spread.

On export to HTML tab stops are converted to non-breaking spaces ( ). Sometimes the width of the all nbsp-s becomes different than the width of the tab stop. When document which contains grid-like data is exported to HTML its columns are not aligned.

When a field result fragment has multiple lines only the first and the last paragraph get the proper paragraph style properties.

If the document contains a simple field without run inside, the import process fails. 

      <w:fldSimple w:instr="page" w:dirty="true"/>

The same document with a run inside the field does not cause an error

      <w:fldSimple w:instr="page" w:dirty="true">
        <w:r>
          <w:t>1</w:t>
        </w:r>
      </w:fldSimple>

When floating image is all of the following: 
- is anchored to paragraph inside a table with negative offset.
- is with text wrapping "Behind text" or "In front of text"
it should be positioned outside of the table. Currently the image is always positioned fully inside the table.
