It happens on connect, but you are notified asynchronously as you are in 
fail safe mode.
Note that you can max log in once for the user (loginName) and NOT for

To have more such 'singleton' clients you need to use different login names.

As said in my posting from 2007-09-10 you should check your multi 
threading approach,
probably it is necessary to dispatch the code to the X-Window main loop 
thread,
