Hi,
I did a SVN update from revision 632 to latest (rev. 652). I then emptied the private data dir.
When I start chat, first it shows the nick name input dialog (it is not supposed to) - and after that it does not connect. User list does not show, and when I write something it says "you must be connected to write a message".
Both nick and channel params are supplied as _GET params.
I emptied my browser cache also before trying.
In rev. 632 I did not have these problems.
