The Log Window (Window > Log Window) displays a summary of what BusyCal is doing. If something isn't working right, check the log window to see if it provides any clues. When errors occur, a message is printed in the log with thee asterisks (***). For example, if you are syncing with Google Calendar and the Google server is temporarily unavailable, an error message will be printed to the log like this:
*** GoogleSync: temporary error (Service Error: Could not generate feed.)
