VNC server free edition 4.1.1 !!! Crash !!! (fwd)

[mixed@freemail.hu]

Hi All,

I run this server in service mode and when I am conneced to server 
and trying to move a window back to the screen  - which is out of the screen 
for some reason - server crashes. 

I am using a terminal program  (Century Term V 7.2) and its window 
sometimes - I don't know why - goes out of screen and in a normal 
case - when I am using it on a local PC - I can put it back to screen by a 
right click on its taskbar icon and using 'move' menu and arrow keys.

But when I try to do it from other PC (connected to a PC with VNC 
server) when I chose 'move' menu, connection freezes and I cannot 
connect again.
On the target PC today I have found a standard window of Windows 
(WinWnc4.exe application error 'memory cannot be read...') and service 
did not work.
It happens on Win2k Prof and WinXP prof also.

Can anybody tell me is it a VNC bug or something else?

Best Regards,
Zoltan

I have attached the error screen:
