Re: 'status' form and disposal problem

How could your _timePanel variable be disposing while the user double-
clicks a status bar panel if the dispose of _timePanel was the result of
user interaction?

Do you mean _timePanel is disposed when the user double-clicks the status
bar panel?

If the time panel is an application-wide shared resource (i.e. a class
member not an instance member) then you might want to override the time
panel's closing event and just hide the panel instead of letting it
close.  Then, you could ensure you dispose that panel when the main window
closes.  Although, if it's dependant on the main window I would question
why it's not an instance member instead of a class member.
