When I was running an application then on pressing a key the following message came: <br><br>X Error of failed request: BadMatch (invalid parameter attributes)<br> Major opcode of failed request: 42 (X_SetInputFocus)<br>
Serial number of failed request: 7345<br> Current serial number in output stream: 7347<br><br>It seems to be something related to graphics, but can't understand. After the above error came the application got terminated.<br>
