Bug found on Open Visual Trace 2.0.0 (Universal/Portable).

If whois is not installed, the "Who is " window shows the message "A moment please..." and no error is prompted.

It took me several minutes to realize what that the problem was. Although resolving the problem was easy, it would have been nice to have a warning or error telling me that the whois command was required.
