Dear Brian, Normally I'd expect that a workspace saved from a previous session and loaded at the start of the current session would cause this kind of anomalous behaviour, but that doesn't explain why the Rcmdr starts up properly in a second (concurrent?) session, nor why it doesn't start up properly when R is run with the --vanilla switch.
Can you report the result of sessionInfo() at the start of a session? If all else fails, you could try uninstalling and reinstalling R and packages.
