OCTGN

I listed this under feature, because it’s not a bug, but it’s definitely what I would call unexpected behavior.

There are many dialog boxes that perform the same action whether they are closed by the ‘Ok’ button or the red ‘X’ in the top right corner.

Let me give a specific example. If you select the action, ‘Draw X Cards’, a dialog box will appear, prompting for a number of cards to draw. If you close the window by clicking the red ‘X’, you will still draw X cards (as opposed to drawing no cards, as would be expected when closing the window like that). The same is true for options like ‘Look at the Top X Cards’ or ‘Look at the Bottom X Cards’.
