I've had a window focus issue for many months and it would help me to know if anyone else is observing it. it's not clear if it's a bug or a non-quartz window manager issue. Perhaps it is normal behavior and I'm misinterpreting. If I toggle between X11.app and other OS-X apps using command-tab, When X11 comes to the front, all X11 windows come forward, in front of any open non-X11 windows from other OS-X apps. If I'm in another OS-X app and I activate X11 by clicking on one of the X11 windows, X11 comes to the front, and the window I click on accepts keyboard input, but all the X11 windows remain behind the non- X11 windows. Perhaps that is normal for X11 windows that I didn't click on. Definitely odd for the window I clicked on. All the symptoms go away when I command-tab out of X11 and back in again. Environment is Enlightenment 16 window manager, with X11's Full-screen mode off (not checked), Leopard 10.5.8, Macbook Pro Everything else checks out great on the new release. Symptom has existed for at least 2 years through several releases. Jeremy had me file a bug a while ago just to document it. If nobody sees this, that will help me to know my wm is just plain broken and it's time to recompile.
