Currently, caret continues to blink even when typing or navigation is in progress (e.g. arrow key is pressed and held), which is inconvenient for the end users. Instead, the caret should stop blinking during these operations, similarly to industry standard apps like MS Word and OpenOffice.

Page field in header (or footer) of document created with mail merge is always evaluated to 1, instead of the number of the current page.

Possible workaround (attached):

- Do mail merges one by one
- Set header/footers anew to contain PAGE fields in each document
- Set FirstPageNumber = 1 to each first section in each document
- Merge with RadDocumentMerger

When a preceding paragraph's size is increased, for example - font size is changed, or paragraph is split to two, then the selection of the consequent paragraphs is wrong. When the cursor is on the second line and attempt to select some part of it with the mouse is made, the first or the third line is selected.

Steps to reproduce: 
1. Create two paragraphs with multiple lines
2. Insert new paragraph after the first paragraph
3. Try to select second line of the third paragraph with the mouse

Observed result: First line is selected instead of second line being selected

RadDocument instance leaks through StylesGallery when RadDocument is set multiple times in a sequence to RadRichTextBox - for example by setting RadRichTextBox.Document property multiple times.

Steps to reproduce:

- Start application containing RadRichTextBox with StylesGallery

- Execute this code on a button click: 

            this.radRichTextBox.Document = new RadDocument();
            this.radRichTextBox.Document = new RadDocument();

Observed: RadDocument leaks through the styles gallery.

The pgMar element might be present but the margin information might be missing as shown below:
<w:pgMar w:header="720" w:footer="720" />
At the moment this overwrites the section margin information with 0. Instead the margins should remain as is.

Fix available in LIB Version 2018.2.820.

Workaround is to enumerate the fields and update them separately.
            foreach (var field in this.radRichTextBox.Document.EnumerateChildrenOfType<FieldRangeStart>())

The caret (cursor) is drawn over letters. This is unpleasant, especially with small font sizes. The issue is even more noticeable when the zoom factor is bigger than 100%.

NullReferenceException is thrown when measuring a document with floating image as the first element on a second page. The same problem can be observed during copy/paste of content, but with slightly different call stack: 

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.Windows.Documents.Layout.LayoutBox.get_ValidParent()
   at Telerik.Windows.Documents.DocumentPosition.GetCurrentParagraphBox()
   at Telerik.Windows.Controls.RichTextBoxUI.RadRichTextBoxRulerController.GetCurrentParagraphBox()
   at Telerik.Windows.Controls.RichTextBoxUI.RadRichTextBoxRulerController.AssociatedRichTextBox_LayoutUpdated(Object sender, EventArgs e)

Depending on the document structure, an InvalidOperationException with message "Removed LayoutBox should not be split. Such operation will result in invalid document structure." could be also thrown. A sample call stack is:

Telerik.Windows.Documents.Layout.LayoutBox.CreateNewFragment(Telerik.Windows.Documents.Layout.LayoutBox currentLineStartNode) 
Telerik.Windows.Documents.Layout.TableCellLayoutBox.MeasureOverrideInternal(Telerik.Windows.Documents.Model.SizeF availableSize) 
Telerik.Windows.Documents.Layout.TableCellLayoutBox.Telerik.Windows.Documents.Model.IBlockContainerLayoutBox.CallMeasureOverrideInternal(Telerik.Windows.Documents.Model.SizeF availableSize) 
Telerik.Windows.Documents.Layout.BlockContainerLayoutHelper.CheckAllFloatingBlocksAreIncluded(Telerik.Windows.Documents.Model.SizeF availableSize)

Type: Bug Report
When document with large images (the original image cannot fit on the page without resizing) are exported to PDF, the PDF document is visualized distorted by Adobe Reader.

The issue is regression, introduced in 2017 R1 SP1.

- Use images that can fit on the page.
- Zoom RadRichTextBox to scale which allows the large images to fit fully on the page.

The fix is available in LIB Version 2017.2.627.

The exception is thrown by the SystemFontsManager internal class from Telerik.Windows.Documents.Core, so it can observed when using RadPdfViewer, RadRichTextBox, RadSpreadsheet.

The reason is not clear, posssible causes are:
- Corrupted fonts after upgrade from Windows XP
- Enabling of Block untrusted fonts feature ( )

The call stack is as follows:

System.TypeInitializationException: The type initializer for 'Telerik.Windows.Documents.Core.Fonts.SystemFontsManager' threw an exception. ---> System.IO.FileNotFoundException: Unable to find the specified file.
