Do sequence:
1. Open any image;
2. Modify it so that PI will want to save change if you will want to close the image (for ex., change Id);
3. Press Maximize button on image's frame (top-right corner) to expand it to full working area - notice that 4 buttons to control image's window (Iconize, Shade, Restore, Close) are now located in top right of the PI main window, just below three buttons that control PI Application window (Fig 1 below).
4. Try to close the image window with the Close button - dialog on possible lose of unsaved process will apear, notice that at the same time those 4 buttons that control image window will dissapear at the top-right corner.
5. Say NO in the dialog - 4 control buttons will remain to be hidden, with this you lost ability to easily control your image window expanded on the screen (workaround is to do something like Window-Cascade, ...). See Fig 2.
As for me - this is definitely bug (was it reported already?).
Windows 7,
