A mate of mine uses Mirc 6.35 and when he doesn't do anything for a while he disconnects.
All his other applications keep on running, so the line is in order ( theoraticly .

Do some of you have zome knowledge with these things?

I already asked him to send me the /debug @debug report. So that will come also as soon as i have it.

*edit,

this happens on the ogamenet.net IRC server.

Seeing the actual disconnection message would help eliminate some of the possibilities.
This message would be sent to his status window, so no debug is required at this time.

Try this and see if it helps.
