A Steam client update is now available. To apply the update, click the File menu inside of Steam and then select "Check for Steam Client Updates...". The specific changes include:

Steam Client

• Made connections to misbehaving content servers timeout and retry a new server correctly
  
• Fixed the client sometimes forgetting a game exists after a content update on Steam
  
• Fixed several rare crashes and memory corruption bugs
  
• Workaround for a Firefox 3.5 bug where they activate random windows after minimizing which would confuse the state of some Steam windows
  
• Fixed internet tab in the in-Steam ServerBrowser not updating sorting as more servers are refreshed
  
• Fixed the first time launch "Installing ..." dialog which is shown while installing things like DirectX for a game taking too much CPU and making the install take a long time
  
• Fixed the sorting of the games list to be case insensitive and fix the mini-games list to use the same sorting method as the full games list
  
• Fixed Change User menu option not logging you out correctly
  
• Fixed one case of downloads getting stuck
  
• Fixed a potential crash in D3D8 games switching between windowed and full screen caused by the in-game overlay
  
• Fixed unnecessary minidump when in offline mode
