Kerbal Space Program

Kerbonaut Experience is an important aspect of game progress.

When deciding on wether to send a Kerbal on a mission or not, the player is supposed to be able to check the activities of the Kerbal that yielded his prior experience gains by looking at the tooltip-window in the astronaut complex.
However, the player is unable to check the experience flags of the bottom-most Kerbals in the Astronaut Complex in case the tooltip-window moves out of the screen.
Since the tooltip-window is bound to the cursor position, targeting a Kerbal in the lower part of the screen will inavertedly force the tooltip window outside of the screen, thus preventing the player to check that Kerbals experience flags.
Moving the mouse upwards will make the tooltip window move in visible boundaries, but the Kerbal whose information is accessed will be another.

Thus players will not be able to view the Kerbal statistics of Kerbals which are pretty far down in the Astronaut complex list.
