For the program "gqview-win-188.8.131.52.exe",
the windows layout is the 3rd radio box
the order of windows are:
There is "Image" is on the left side (completely filled)
There is "seperator bar" in middle
There is "Tools" is above the "Files" on the right side
now, I move the "seperator bar", to the right almost an inch to the screen, that is the Tools and Files are compressed to 1 inch side, then i close the window, and reopen, the "seperator bar" position is "not" at the same place, as it should be.
With other layouts it is working fine.
