Sometimes when I have another app's window obscuring IDEA's window and I move my mouse over the IDEA window, the IDEA window will come to the foreground and steal focus. Other times it'll grab focus (blinking its button in the task bar). Other times, it'll do nothing (which is what it should do).
It seems to happen when I have something selected in the Project or Structure panel and I happen to move the mouse over or near it. For example, take a look at the two attached images. In IDEA_MouseMove_1, I have a browser obscuring most of IDEA, with the mouse cursor over the browser window but near the selected entry in IDEA's Structure panel. In IDEA_MouseMove_2, I have moved the mouse cursor over that selected entry, and without my clicking any mouse button, IDEA has brought itself forward and taken focus.
I do not have any XMouse utilities installed, and I have not turned on Windows' "Activate a window by hovering over it with the mouse" feature.
This may onl happen when the item in question (the one that's selected in the panel) is wider than the panel itself (and so there's a tooltip involved). I haven't been able to prove that conclusively, but I am pretty sure it's a factor.
The other thing to note is that I keep my Task Bar hidden and docked to the top of the screen (so it only shows when I jam the mouse to the top of the screen).
Is anyone else seeing this, or able to reproduce it?
