TWW lua error = [, character]

[n0proxy]

Since TWW, I've been getting a lua error pop up quite often when clicking on other addons or when in the Blizzard options menu. I don't notice anything actually broken because of it, but I'm seeing it pop up quite often.

Hi there,
I second this. Same behaviour. Pretty annoying.
Tried to fix it on my own, but didn't get very far with debugging.

This should be fixed with the next update. Try version 2.0 of WidgetTools (currently in beta) - used by 3.0 beta of Movement Speed.
