This may be part of bug 93877, or it may be a bug with KDE. It seems that Mozilla binds to ALT-TAB when the Location bar has focus. I'd assume most OSes don't allow this, but under Kde 2.2.2, it appears to work. STEPS TO REPRODUCE: 1) Open Mozilla. 2) Open some other application. 3) Give Mozilla keyboard focus. 4) Click on location bar 5) Type some text. 6) Hit ALT-TAB. EXPECTED RESULTS: Next application in window order should obtain focus. ACTUAL RESULTS: Nothing happens.

This isn't quite what's happening. Rather I think the URL bar dropdown is doing an XGrabPointer, so all events are being taken the application. Personally I don't like this behaviour either: it is very annoying when you forget what URL you're typing and try to switch windows/desktops to look it up.

Yes, but dropdown-like things should XGrabPointer in general, no? Reporter, if you completely turn off autocomplete does the problem go away?

bz, I'm not sure you're right in this case, but seeing as I am not going to produce a patch I won't comment further than to say that ideally, the URL drop-down would be like Mac-style "sheet dialog", and window modal only. There are some obvious difficulties with implementing this in X of course.

Nope, with AutoComplete off the bug is still there. Curiously, I still see a grey bar appear right below the text entry bar with autocomplete off. I will attach a screenshot.

Another, probably related, note: When trying to take the screenshot with the GIMP, I was unable to use a window-only screenshot. GIMP printed "xwd: error: Can't grab the mouse." to the console. This problem occured with and without autocomplete. This problem does not happen if the location bar is not active.

Reporter, what bz meant was the "Show list of results" option under the Advanced button. If you turn this off, then you won't get a drop-down list, and won't see the problem. The error from gimp is perfectly normal behaviour. What's happening is that Mozilla is doing an "XGrabPointer" call - this means that all mouse events get relayed back to Mozilla first, for it to deal with. This is necessary so that if you click somewhere else, Mozilla knows to close the drop-down. The same method is used in all applications for their menus; it's the standard way of doing this on X.

setting summary to describe the real problem. blizzard, any ideas?

Ah, K. Turning off the "Show list of results" option, I no longer see the bug.

Could this be a duplicate of bug 66834?

I think it is, bug 66834 comment 7 being the crucial point I think.

yes, it is. *** This bug has been marked as a duplicate of 66834 ***
