Handle single Alt in Compare tool

[browny]

Not too long ago, there was my request to enable scrolling on the wheel of hovering mouse pointer in the bottom pane, and it appeared that the scroll was working.
However, sometimes it does not.
One possible case is single press of Alt key. There is no menu in the dialog, and focus seems to be going in the direction of the system menu (minimize, ...).
But user sees no changes, while the dialog becomes unresponsive to various action, such as most of the keyboadrd and scrolling panes on mouse wheel (Down key will show the system menu, or another Alt will restore normal input). Not quite a bug, but certainly unpleasant feature.
Could you try to fix this issue somehow?
Maybe, reset single Alt after short time.
System menu should be still accessible with Alt+Space.
