toolbar won't hide

[Fak3]

When i click on the "hide >>" button on top of the toolbar nothing happens.

In chromium console i het en error message upon click:
"event.layerX and event.layerY are broken and deprecated in WebKit. They will be removed from the engine in the near future."

In firefox nothing is printed on the console

Linux,
Chromium 18.0.972.0
Firefox 9.0.1

Same problem. Not getting any sort of console output so I have no idea what the problem could be. Using Chrome 14.0.835.186 and Firefox 7, both on Ubuntu 10.04.
