During and after the running of this BTM file, my logon session is hosed! Explorer barely works. A "^C" appears in the console and an unrelated BTM starts. Caps-lock comes on. Many apps are unresponsive, including TCC. Things stay this way after killing TCC from TaskMgr. All I can do to get things working right is logoff/logon.
