[maplab-users] Strange behaviors

[galassoa@tin.it]

Hi everyone...
i'm starting to work with MapLab 2.0rc4 on Windows2000.
After installation of PHP4.3.1, mapserver 3.6.4 and maplab2.0rc4 i've noted
a strange behavior of MapEdit.
I've opened an existing map and clicked on "Preview". Then the first view
appears. But clicking again on zooming produce a blank image.
Another thing is that in the legend don't appear the list of the available
layer.

May someone help me to understand where is the problem ?

Thanks in advance,
Alessandro.
