interesting thing here.

my app (made in C#) works great.
It has a worker thread which is created from/executed from the main form if the user clicks a button.
I have also created custom delegates and events and works very well.

when an event is raised from the worker thread signalling that it has connected to a server successfully or perhaps the server disconnected the session or even the user disconnected - it runs the event successfully. GREAT!

now the fun part

if I add and execute another form, heck even if its on the one main form, if i add a treeview and start to populate it with data from an array or even manually, as soon as the first node/entry has been populated the entire form hangs/locks up!

I do not know why and its frustrating.
Now, if i create a new project and just have 1 main form, no threads or anything and populate the list myself or even through an array of items, it populates fine! no errors, lock ups or hang ups!

why? does anyone know?
