I'm a bit dissapointed now.
I started your GDemo.exe and tested one situation that could happen in a
real life, when I got this Access violation ...
-------------------
"Die Anweisung in "0x00402272" verweist auf Speicher in "0x00000018". Der
Vorgang
"read" konnte nicht auf dem Speicher durchgeführt werden.
-------------------
What I did was simply start one GDemo.exe as Local-Server, then start
another GDemo as Client and connected to "localhost" (where the server was
running). Then I added a few objects (both GDemo.exe processes saw the same
objects, meaning that the connection was working). When I had 40.000
objects, I closed the Server (this should simulate that the connection got
lost). And this is where the Access violation popped out on the Client side.

Is this a problem of this particular Client?
