[maplab-users] Help with 'buttonizer' error

[Lorna Grimm]

I'm using mapedit from maplab3.0pre1, installed from .zip 
downloaded under ms4w directory. 

I've edited the xml config files to suit my setup, then I've 
used mapedit to open the map file from the tutorial, and the 
map preview frame displays the following warnings and error:

Warning: main(c: 
mpp\htdocs\ms4w\apps\chameleon\htdocs\common\buttonizer\butto
nizer.php): failed to open stream: Invalid argument in 
c:\xampp\htdocs\ms4w\apps\chameleon\htdocs\widgets\TextButton
.php on line 30

.php on line 30

Fatal error: Call to undefined function: buttonize() in 
c:\xampp\htdocs\ms4w\apps\chameleon\htdocs\widgets\TextButton

Any ideas what I'm doing wrong ?
