[Users] really strange..: "burried popup"

[ivan marchesini]

Hmmm

many many thanks Ryan and Matt..
at least now I know it's not my fault... (but I have spent one day on
this problem :-(  )

now the new problem is:

How to destroy the unuseful and automatically load the useful
 layers??

I will try to find a solution.. but any suggestion is welcome..  :-)

Thanks

Ivan
