If you are seeing strange behavior in the VI Analyzer UI (or the Results Window UI), you can add the following LabVIEW INI token to help with debugging:
LVdebugKeys=True
This token will enable error handling dialogs to appear while using the VI Analyzer UI (or the Results Window UI). The token also adds a lot more debugging capability to LabVIEW than this, but you can explore those avenues with a google search if you so desire.
