[edit] manager does not responds ("half window")

Hi,

I’m scared about what is going on, on this new site (almost complete) : today the manager displays only menus and right windows but stay in a loading state (please wait during page loading.. or something - it’s FR) and the tree never comes.??

I did not find something about such an issue here (?)

Yesterday all what ok. And I guess no one else was able to do something.

This is the same whatever the login I choose.

I made an sql export yesterday just before closing. The Front site is still alive (but there’s something weird with an alternate img for the flash banner). The FTP access is still also ok.

Did anybody saw this before ? Where should I investigate ?
Thanks a lot.

[edit] oops ! ONLY with FF (ie 6 : everything ’s ok !!?
