When I resize the chat window or when I pass !list command in
channels. My display screen resolution becomes 480 x 600 resolution and 16 colors . then this error message shown .



After I restart this error message shown



I am facing this problem only while using mirc . Other IRC clients lacks many features that mirc have . so I am addicted to mirc . But this error is causes much problem for me . I checked RAM memory too, no problem in RAM.
