Hi.
It happens when I try to close a channel window, and my computer is lagged or client is lagged. I am using a PII 233 MMX, 327MB RAM, Windows 2000 Profesional. (latest version of mIRC 6.16)
Thank you for possible answers, and as the guy above suggested I am not minizing the client, I am closing a channel window only, at a lagged computer/client.
