           Summary: Window title bar double-click to return from maximized
                    state sometimes makes window full sized
           Product: Wine

I use WINE to run PFE, a text editor.

I've noticed recently that behaviour has changed when double-clicking the title
bar.

Normally, double clicking title maximizes window, and double clicking again
minimizes window.

What now *sometimes* happens is that the first double click as expected
maximizes, but the second double click returns the window to its normal size
but then instantly changes the actual window size to the maximum possible (to
the screen size).  This is *not* the maximized state, because double clicking
now - no matter how many times - does not change the window size.  The window
has actually been resized (and so further double clicks are converting a
screen-sized window to maximized, and then back to screen-sized).

At this point the window has to be manually resized back to something
non-maximum.

My suspicion here is that I might be issuing from the mouse a very rapid
*triple* click, and there's some kind of race condition, where the third click
is causing the observed behavour; and that this is why it happens *sometimes*
only.
