Problems arise when an attempt is made to insert a bookmark, the selection is empty and focus is not in the editing iframe.

Such bookmarks require the creation of a range. Because of the IE8 bug(feature?), the range is incorrect. The bookmarks are used to restore the cursor position when undo/redo operations are performed.

If focus is brought on the editor iframe for the purpose of inserting a bookmark, any opened dialogue window is minimized, which is very annoying.

The same happens when a special character is inserted or when the acronym dialogue window opens (because it may need to create a range to get the current acronym/abbreviation).

The issue does not exist in TYPO3 4.1 because the cursor position restoration feature is not available in that branch. Acronym was not enabled in IE in that branch either.
