| Hi,
=20
I have developed a virtual classroom with a shared whiteboard component. =
I
use an extended version of the macromedia whiteboard component, a few =
tools
added but uses the same technique. I have several room instances. My =
client
is behind a firewall that blocks port 1935 and therefore I use port =
8080.

And now the bug: At some point the whiteboard stops working and no one =
is
able to draw. Very often, it stops working when about 100-110 shapes are
stored in the shared object. I have a trace on some variables to see =
what
happens when a users tries to draw. When pressing the mouse button a
interval is created and when releasing the mouse button the interval is
cleared. I=B4m tracing the intervalID and when the whiteboard stops =
working,
the intervalID is empty. No intervalID is created and your not able to =
draw.
This scenario occurs almost every time when a user behind a firewall is
connected to the room. It does very rarely happen when users that are =
not
behind that firewall are connected, but it has happened when I conneced =
to a
room localy on my computer. This thing drives me nuts. I would really
appreciate if someone have some ideas about this.

Thanks in advance!
