If you get an error, try simply using "RETALL" followed by "XMANAGER"
at the idl> prompt. If you are not saving any widget state information
in uvalues using /no_copy, this will often work just fine. If you
are using uvalues with the /no_copy option, the "retall" will cause you
to be unable to re-enter the xmanager successfully. In this case,
I do this: "retall", close the top level widget base using the window
manager (it wont always disappear immediately), then type "xmanager".
This will cause the widget hierarchy to be destroyed, and you can
restart it without restarting idl.
