Does it help if you leave the files in /usr/bin, but explicitly specify
the path to the program (e.g., /home/Ed/telnet.exe)?

Sounds like a permission issue.  What does "ls -ld /usr/bin" show?
This may be a red herring, but try the following command:

chmod a+x / /bin /lib /usr /etc

If this helps, your trouble may be with traverse checking...

Also, can you post the permissions on the original files and the copies in
your home directory (both "ls -l" and "getfacl")?
