MSN Messenger sta evolvendo...
A new build of 
  MSN Messenger 7 has been sent to BETA-testers just moments ago. 
  
UPDATE: One noticable change is the new Audio 
  icon in conversation windows. Apart from that, this non-public build 
  7.0.632 looks no different than the leaked 604 build. 
  
The following Known Issues have been reported by 
  Microsoft:
- Winks from 7.0.632 can only be sent to 
  another build 7.0.632. The leaked build (7.0.604) and the public 
  beta (7.0.425) cannot receive winks from the latest BETA (this will be 
  fixed in the refresh). Issues may be experienced with Winks if the 
  installed version of Macromedia Flash is not up to date.
- New 
  MSN Mobile features such as sending a text message to a contact from 
  your mobile phone or Offline Messaging will not be immediately 
  available.
- The MSN Messenger BETA build will not be added to 
  major firewall provider safelists and may cause firewall software to 
  display a security error. 
- Full-screen Video Conversations may 
  crash on Windows 98.
- Installation of the BETA version 
  on Windows Media Center Edition is not supported.
- It is 
  recommended that Windows 98 and Windows ME users upgrade to 
  Internet Explorer 6.0 before running the new BETA.
- Some 
  international character sets or "Double Byte Character Sets" may overlap or 
  cause the font and/or font size to change.
- The "Customer 
  Experience Improvement Program" menu item under Help may be inactive. To 
  get around this, please click on Tools > Options > General.
- 
  When signing in as anything but "Online", the ad in the main window is 
  not clickable.
