Text highlighting problem: a follow-up

Many people wrote to confirm the text highlighting problem mentioned last time. Avariety of possible solutions were suggested but there was no convergence on any one solution. However, two readers (Stephen Panarelli and Dave Ritter) did agree that the cause for the symptom on their Macs was a problem with corrupt or incorrectly located print spool files (as found in the Print Monitor Documents folder). Deleting these files, or disabling Print Monitor solved the problem. Finally, a couple of readers noted that this problem has been around through several versions of the system software.
