Comment 2 for bug 1023165

Confirming that enabling said option breaks changing the input method through the menu in the notification area icon. Although the selected input method shows as checked in the menu, input actually continues to use the previous input method. It similarly breaks the input method changer menu in the separate language panel, except in that case even the checkmark does not change.

Also, even if the "Share the same input method among all applications" option is not set, changing input methods with the GUI (as opposed to the keyboard short-cut) is still flaky--sometimes it just ignores me and stays on the previous input method. The configuration that seems to work the best is "Share the same input method among all applications" = Off and "Show language panel" = "When active", and then I use the language panel at the bottom-right to change input methods. But even that sometimes gets stuck.
