Microsoft has updated Office 2011 to version 14.4.2 with just a few improvements. The release fixes a nagging bug that always required product activation after restarting a Mac with a Fusion Drive (though you may have to enter your activation details one final time after installing this update). It also provides two PowerPoint-related fixes — one for an issue that made the Undo button disappear after saving a presentation to a local drive, and another that caused YouTube link data to disappear after saving a presentation.

Mysteriously Moving Margins in Word
In Microsoft Word 2008 (and older versions), if you put your cursor in a paragraph and then move a tab or indent marker in the ruler, the change applies to just that paragraph. If your markers are closely spaced, you may have trouble grabbing the right one, and inadvertently work with tabs when you want to work with indents, or vice-versa. The solution is to hover your mouse over the marker until a yellow tooltip confirms which element you're about to drag.
I recently came to appreciate the importance of waiting for those tooltips: a document mysteriously reset its margins several times while I was under deadline pressure, causing a variety of problems. After several hours of puzzlement, I had my "doh!" moment: I had been dragging a margin marker when I thought I was dragging an indent marker.
When it comes to moving markers in the Word ruler, the moral of the story is always to hover, read, and only then drag.
