#92 Clicking in specific spot closes docked window

[Ben Olden-Cooligan]

To reproduce:
1. Open a window (this works with engine analysis, game list, and probably more)
2. Ensure it has its own area not shared with other tabs (e.g. right click on the tab and choose "Move to bottom")
3. Place the mouse on the left side of the window. Move the mouse one pixel to the right of the resize handle (the mouse should display the standard arrow).
4. Left click.
The window closes unexpectedly.

Platform: Windows 8, fresh install of scid 4.6

I have had this happen to me accidentally when trying to click the Start/Stop button in the engine analysis window. It's quite annoying because it messes up my window layout.
