I am using XUbuntu 11.10 with xfce version 4.8
I have a QT application running all the time. I can open terminal and type in this terminal. But after a long run, if I open terminal I cannot focus the terminal window and type in it. Even I cannot close the opened terminal window. However, I can press Ctrl+Alt+F1 and open graphic less virtual window, which confirms that keyboard is working. Which xfce program or config controls the focus event ? Any kind of clue would help me to solve the problem.
Thanks in advance,
