[Chameleon] Query Widget

[Tracy Howlett]

I'm trying to implement the Query widget but I'm getting the following
error:

PHP Fatal error: Cannot instantiate non-existent class: cwcpopup in
C:\apps\cwc2\htdocs\widgets\Query.widget.php on line 56

I can't find any documentation on the cwcpopup class (or lack thereof!).

I'm also having problems getting the PrintWidget and HelpWidget working.
Are there any known issues with these widgets?  

My setup:
MapServer 4.0.1
PHP/MapScript 4.3.4
Chameleon 1.1
Win XP (must also work on Server 2003)
