Ah, to return home after an extended tour of Boston and the Northeast, complete with an ongoing bout of the Martian Death Flu. There's nothing like returning to hundreds of messages that I didn't read while on the road (mostly mailing lists, luckily) and to a foot of snail mail. In the confusion, I managed to accidentally send two personal messages (and a quick apology) to all 9,600+ people on the TidBITS mailing list, resulting in a number of messages from people who were relieved to see that even we so-called net experts can screw up royally from time to time, proving that we're only human. Or perhaps we're actually sophisticated artificial intelligences? [ACE]
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.
