Uneasy coexistence of 1.3.7 and 1.4.0pre2 (Windows)

[Paul A. Rubin]

Note to beta testers: I installed 1.4.0pre2 parallel to 1.3.7 (Win XP 
Pro), and when 1.4.0 rewrote my preferences file, all the viewer 
settings were vaporized.  No big deal to get them back, once the 
defibrillator brought *me* back.
