Hi,

I found a strange behavior: i was using Chrome, Firefox and Safari each one with a different logged user.
Then, working at my theme i used this code:

global $user; 
db_query('UPDATE {node_counter} SET daycount = daycount + 1, totalcount = totalcount + 1, timestamp = %d WHERE nid = %d', time(), $node->nid);
db_query('UPDATE {history} SET timestamp = %d WHERE nid = %d AND uid = $d', time(), $node->nid, $user->uid);

I was trying to increase total count of a node called by views.

And then, after refreshing the page, all users were user 1...i unistalled the modules and even so the session for all browser was only one, the uid =1.

I wasn't working with sessions, only with the history...so why did it make all this mess?

thanks
