My Ubuntu 11.04 (installed 2 days ago) is misbehaving.
When I try to upload an image via Flickr or Imagekind my browsers (Firefox and Chrome) crash. It even causes the "Run a Command" window not to respond. When I run
killall -9 <browser-app-name> the browser window and space on the menu bar remains occupied / in an unusable state.
This problem started happening a couple of days ago. It also has a tendency to crash my window frames and effects, which i use
compiz --restore to fix.
What could be causing this and how can it be fixed?
