Here is the situation:
Xion is NOT in "always on top" mode
Xion is minimized
I click the taskbar icon, and xion is maximized, but not brought to the forground.
So if there's a window where xion maxmizes to, it doesnt appear, and since its not in the task manager, you cant Alt-tab to it.
Just a minor annoyance, but thought I'd throw it out there!!
