i have here the same problem that widgets would not install... It looks like they are well installed (i think they are).
error in ie8:

what can i do about this.
Ive downloaded from the dayly build the newer WidgetAreaEditor.js, replaced the old one but got on all the pages errors... i think too much changed in the dayly build.
btw i'm using silverstripe 2.3.4.rc1
