And with FreeBox (French provider) the connexion have some problem ( When the listener is on FreeTelecom( I try with 2 connexions points and 3 Freebox(Freetelecom router))

1 message of 4k every 5ms

The new viewer will use a 20ms mouse queueing for LAN.
Still responsible enough.

For WAN we possible can add a 100ms queue..... any idea how many mouse mouves you can see in second ?

+Mouse move during connection -->connection lost
Fixed: I guess this problem must also exist in 1.0.1 but manifest less.

Feel free to try new viewer v2 at http://sc.uvnc.com/v2/
maybe fix issue of lost packet, please try it and let us your feedback

Thank for you response,

but that not resolve my problem, it really a problem with Windows and FreeTelecom because when i try this under linux that work so fine.

the problem appear only when the server establish connection to the viewer ( ACK have crazy value ) ( SingleClick or Add new CLient on winvnc )

use same MTU size for windows ?

The only difference between outgoing and incoming is that the buffers
are set depending on the originator.

In case for the outgoing connection, winvnc use the value's from the viewer.

The viewer and the server does not set the buffers, but the OS of the viewer PC does

or was it the server PC.....need to check it.
