Okay -- but I still don't get why the message isn't displayed. Other folks can get it. Any idea why not me? My book says it should display the message and go right back to the loop.
Sorry if it's a basic question, but I'm still new to this.

I'm using the trap command to capture any signals received whilst my script is running.
How's the best way of writing the signal and any other error messages to a file/error log' without having to type '2>$1' on the command line after the script name?

tk::messagebox
messageBox(3) User Contributed Perl Documentation messageBox(3)
NAME
messageBox - pop up a message window and wait for user response.
SYNOPSIS
$response = $widget->messageBox(-option => value, ... );
DESCRIPTION
This method uses Tk::Dialog to quickly create several common dialog boxes. A dialog widget consists of a message, an icon and a set of
buttons (see the -type option). After the message window is popped up, messageBox waits for the user to select one of the buttons and
return the button text (note that it's best to check the returned value in a case insensitive manner). NOTE: unlike Tk::Dialog which
creates its widget once and can be used many times, the messageBox window is created every time it's used.
The following option/value pairs are supported:
-default
The case-sensitive symbolic name of the default button for this message window ('Ok', 'Cancel' and so on). See -type for a list
of the symbolic names. If the message box has just one button it will automatically be made the default, otherwise if this
option is not specified, there won't be any default button.
-icon
Specifies an icon to display. On X11 any of the builtin Tk bitmaps can specified. On Windows only error, info, question or warning are
supported.
-message
Specifies the message to display.
-title
Specifies a string to display as the title.
-type
Specifies a predefined set of buttons to be displayed. The following values are possible: 'AbortRetryIgnore', 'Ok', 'OkCancel',
'RetryCancel', 'YesNo' or 'YesNoCancel'.
EXAMPLE
$response = $mw->messageBox(-icon => 'question', -message => 'Hello World!', -title => 'My title', -type => 'AbortRetryIgnore', -default =>
'Retry');
