unfortunately I have not traced it yet, I have read your suggestions on how to do it, but my configuration prevents me from starting the debbuger which is outside a dos volume. I hope I will get useful information soon, this is the error I get when I try copy text from an Xterm window to clipboard while Agent is running (started in background from the same Xterm): X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 24 (X_ConvertSelection) Resource id in failed request: 0x0 Serial number of failed request: 126694 Current serial number in output stream: 126694 I have already reported problems with cut&paste from non-running wine windows to a wine running Agent window: in the worst case I cannot paste text at all, but Agent has never crashed like it does in 20010629
