It would have been nice if someone had told me, several weeks ago, that PWM does not work with Bon Echo, such as today's release, Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1b2) Gecko/20060901 BonEcho/2.0b2 - Build ID: 2006090103.
If I had known that, I would not have been using PWM....
(Easy to make it work: Nightly Tester Tools or MR Local Install [I use the latter] makes almost all "non-compatible" extensions compatible.)
