xsystray was introduced to support a system tray for Qt and it is now used for Odin, too. And nowadays, more and more programs on OS/2 use this feature. However, unforunately, I had a problem with xsystray. If I add xsystray to XCenter, XCenter crashes when it re-appears on auto-hide mode. To see XCenter, I had to show XCenter once more. Because of this, I have not used xsystray. However, xsystray is an important feature. So I tried to fix this problem. And I've found a workaround. It's very simple. REBOOT!!! I did REBOOT with wishing lucky. When OS/2 appeared, XCenter did not crash any more. However, if a position of xsystray is moved, the same problem occurred again. And I had to REBOOT. If you also have this problem, reboot your computer after adding xsystray to XCenter. Nevertheless, if same, then try cold-reboot. That is, shutdown, power-off and power-on.
