Corner-case issue noticed on TC and PiCore:
If a user clicks on any icon preceding the terminal icon, and summarily dismisses the window that comes up with the ESC key, rather than using the mouse to close the window, renders ALL wBAR icons insensitive to further mouse clicks.
Fortunately, the fix is simple from a user standpoint doing any of these:
1) Don't use the escape key to dismiss windows.
2) Click anywhere on the screen to bring up the hierarchical menu and go back to using icons
3) Go into a virtual terminal (ctrl-alt-f1) and back (ctrl-alt-f2) and icons are clickable again.
Minor nitpick on a corner case.
