Alain,
The WriteOCPacket() - sendto error 10035 error has been moved to the
debugging version only so users won't see it. It shouldn't lock your
PC though, I wouldn't be surprised if there's another problem there. In
general, even if you're using SLIP or PPP and are bogged down with incoming
video and control data, you don't have much to send out and outgoing traffic
makes it out OK.
The check box for 'send packet loss reports' has been removed. This
should really not have been there since we want everyone to send packet loss
info.

Subject: WriteOCPacket error - origine

With an FTP stack and an ethernet card on a LAN
or with Trumpet and a PPP connection:
when windows CU-SeeMe receives:

WriteOCPacket[]: 'sento' error - [10035]

it locks the program and require manual closing of the
window it's written into.

Are those a) indication of lost packet to which CU is supposed
to automatically react and lower its cap speed, or
b) local software trouble messages?

if a) what can be done. This ends up requiring that CU be closed
then restarted. Is that normal for the window version of CU?
It prevents using a PC left "on" with CU running as a mean of providing
a visual security check of the room by loging onto it from anywhere.
If the PC got a "sendto" error it stop transmitting and cannot
recover from it until someone reset it manually

If b) How does someone knows that some packets are getting lost?

In any case, what use is the preference "Send Packet Loss Report"
The use of this switch is not explained but if it's there, it must answer
a need. Why would someone NOT want to send packet loss report?

Thanks in advance. Alain
