Official Motorola Library -- In TidBITS-322 we mentioned a PowerPC math library compiled from Motorola's PowerPC SDK. The library was later withdrawn due to licensing concerns and Motorola's intent to release their own version. Though it's a few weeks late, Motorola has indeed released LibMoto, which improves the performance of some floating point math functions on Power Macs. The shared library is available for free (a developers version is also available), although Motorola asks users to register online to download the library. If you don't do extensive number-crunching or graphics work on your Power Mac, you probably won't significant benefit from this library, but some users could see worthwhile performance improvements. I've seen unconfirmed reports of problems using LibMoto with the GeoPort Express Modem and some fax software (surprise!), so be sure to take normal precautions before installing this (or any) system software.

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.
