Bug Description

Stellarium in full screen mode may hide from view regions which respond to mouse input.
These include
- the windows taskbar, especially if in auto hide mode
- almost anything after an AC - battery switchover, power plan change, Alt-Tab
  The effects of Alt-Tab depend on what is running and what the actual tab order is.
- application popup (e.g. task completed, taskbar notification bubble, virus warning)

The Alt-O bug in the ocular plugin (#80609) is an example of an invisible box able to receive mouse input, but created by Stellarium itself.

Usually such conditions are cleared by a mouse click outside the active region.
Many popup notifications have a timeout so the potential problem may disappear in a few seconds.
Those that persist often can cause an obvious problem only if some button is clicked by chance.
Often the only symptom is a single mouse click may seem to be ignored by stellarium.

Stay-on-top applications may be hidden by Stellarium but stay responsive to mouse input indefinitely
e.g. some calculator applications, drag and drop boxes.

The potential exists for a single mouse click in Stellarium to do virtually anything.

This has been observed for versions 0.11.2, 0.11.4 and 0.12.0beta2, all in both standard and no OpenGL2 modes, running Windows 7 Home Premium 64 bit on the following machines

Toshiba Qosmio F60
Intel i7-620M
Nvidia GeForce GT 330M

Alienware M11x R3
Intel i7-2637M
Intel HD Graphics 3000
Nvidia GeForce GT 540M

Observed with Alienware M11x R3 running either GPU.

I have attached screenshots showing an example of what is visible to the user and what can receive mouse clicks.

Is this still an issue in the 0.15 series (Qt5)? I cannot reproduce it.
