Confirming Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050706 Firefox/1.0.5 But works on the lastest trunk build tho ... so something must've been changed. I will do more research on that. Recommend --> Core - Javascript Engine (for now)

jayfromtaiwan@gmail.com: i recommend you don't make recommendations. would someone please reproduce this with a talkback enabled build?

1.0.5 and newest at the moment 1.0.6 are affected by this bug too...

seems to be fixed in 1.5 beta
