Out of curiosity, have you tried restarting XFWM4? The command is xfwm4 --replace, I'm pretty sure. Somebody else probably will know exactly how to kill this. Seems to me XFCE should have switched to LEDs by now. CFLs are *so* 2001 and have mercury in them.

Seems all okay except for a strange notification in the top right that won't go away. It looks like a lightbulb so I'm thinking it's something to do with screen brightness (?). There is no X to close it. I can make it transparent but it re-appears when moused over and can prevent me accessing parts of an application that are beneath it. I know I can make applications 'always on top' but having to do that every time gets annoying. A screenshot of it is here - <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://ubuntuone.com/2R7Mtw9jBmFlhRZC8MqqV3">http://ubuntuone.com/2R7Mtw9jBmFlhRZC8MqqV3</a> Any help will be very much appreciated. I'm happy to turn of all notifications if necessary. Many thanks Dave <fieldset class="mimeAttachmentHeader"></fieldset> </blockquote> </body> </html>
