Greetings...

In Scamper>>jumpToNewUrl if the instance variable currentUrl is a string,
then the message toText is not understood. currentUrl is initialized as an
empty string, and when the default startup page does not load (like when
the Squeak Swiki is down), then when you try to jump to a new URL by
selecting the menu option 'new URL', you get a MessageNotUnderstood:
toText. The work around is to type the new URL into the top window, but it
would be nice not to get the pink debugger window when you select a menu
option :-)
