Since I upgraded to Windows 7 I have been using all of my BlackBerry utilities on my old Windows XP rig. This is because not all of my utilities have been working as they should in Windows 7. Luis let me know that one of my favorite utilities, BBMCP, is now working like a champ in Windows 7. Not sure if this was a recent improvement or not but its worth the upgrade either way.
