The last card (King) when placed manually onto the stack (pile) is captured by the mouse pointer and will follow the mouse, sometimes moving the Queen a little off the stack. When attempting to click on the Ok button in the congratulations window, as the the mouse is moved over this window the card goes underneath (with the pointer going over the top of the window). The Ok button cannot be activated by the mouse, but can be activated by the keyboard Enter button. The buttons in the following window also cannot be activated with the mouse.
This behaviour does not occur when the card is double clicked to automatically place it on the stack.
This behaviour is present in revision 45781 and earlier revisions going back to at least release 0.3.11.
