You have to select a Border Style option in the Paragraph Border & Background dialog. The default setting is None and this does not display any borders.

You probably have a large number of image objects embedded in the text. This can happen when you copy and paste images and text together MS Word. This automatically inserts the images as embedded OLE objects, which uses up a very large amount of memory and computer resources. Inserting a large number of large OLE objects can also have the same effect, particularly on older and slower computers with limited memory.

To solve this problem you can convert these embedded images into external graphics files. Just right-click on the embedded images and select Convert Embedded Image in the popup menu.

Identifying embedded images:
When you click on an embedded image it does not appear as a "negative" image. Normally-inserted images appear as negatives with all their colors reversed when you click on them.

You're probably used to working with a word processor like Word or Open Office. Help+Manual's editor is a little different from these programs and it stores its paragraph formatting in a different way. Because of this it's not possible to select the "paragraph mark" at the end of each paragraph.

The best way to copy paragraphs "cleanly" is to press Enter once in the target location to create an empty paragraph, then copy to the empty paragraph. After completing the copy you can then delete any extra paragraphs without losing style information.

Help+Manual calculates all dimensions in pixels internally. If you display your dimensions in inches or another unit the values are converted from pixels and the results must often be rounded.

If you want to work with maximum precision choose pixels for all dimensions. You will get used to it quite quickly and then you won't experience any rounding "surprises".

Technically lists need to contain at least two items (paragraphs) because the formatting of the list is "controlled" by the first paragraph. You can solve this problem by selecting more than one paragraph or the entire text of a single paragraph before selecting the bullet or numbering tool in the Toolbar.

Alternatively you can also place the cursor at the very beginning of the paragraph (before the first paragraph) before selecting the list tool, this will also work.
