gksudo window loses focus if the password prompt is right-clicked

[Tate Richardson]

I just realized what was going on today, although I've seen it happen before -- but I don't remember if it was the same version of ubuntu (or the gksu package). When the gksudo window pops up, supposedly "grabbing" your keyboard, if a user were to RIGHT-CLICK on the prompt line for whatever reason, two things happen:

First, the right-click menu appears BELOW the gksudo window. Perhaps that was intended? Problem is, though, you only catch it if you either have a keen eye or know it's gonna do that. So there's that...

Second, perhaps BECAUSE of the menu appearing BEHIND the gksudo window, the window directly behind where you right-clicked is now in focus. But you can't know until you start typing, because the cursor in the gksudo window is still flashing, ready for input. By that time, you've already entered a few letters of your passwd, if not the whole thing. If you hadn't yet noticed a problem, or don't expect it to BE a problem (perhaps because the TERMINAL version of sudo DOESN'T show the ****'s for each key press), you've just sent your password to everyone in the chatroom you were in. (if you're that unlucky, and that window was the one that got focused).

What's worse, is that you CAN'T get focus BACK to the gksudo window without knowing what's going on. You can still click cancel, but left or middle-clicking on the actual prompt doesn't bring it back into focus (although the cursor flashes as if it IS in focus). The only way to bring it back into keyboard focus is to right-click again, THIS time the context menu appears ABOVE the gksudo window. Now it's focused. Moreover, further right-clicking doesn't go "through" the window like it did the first time... i.e. it works as intended.

I tried this with multiple window managers, all do the same thing. I'm using Ubuntu 12.04 64-bit, gksu version 2.0.2-6ubuntu1

I can confirm the first part, about the context menu popping up behind the window. Clicking anywhere in the prompt and right clicking again will get the normal context menu back for that line (cut, copy, paste, etc.).

I can not confirm that the window will lose focus. I had maximized Firefox, three terminals, and a Flash application open right where the gksudo prompt shows up. That prompt did *not* lose focus.

Ubuntu 12.04, 64bit.
