2003-10-13 Havoc Pennington <hp@redhat.com>
In the "prefs cause code complexity" department, here's a "sloppy
focus die die die" kind of moment.
* src/display.c (meta_display_grab_focus_window_button): don't
grab in sloppy focus mode, since we were dropping the grab on
window enter anyway this just removes races from the current
behavior.
* src/display.c (prefs_changed_callback): ungrab/grab on focus
mode changes, since we treat sloppy and click differently.
