I have BOINC 4.13 cc and have not had any problem, graphic stays all the time, even if on an "on-off" situation. Have had no problems on any of the last 10 units.

"I also have this question" (Click) ;)

So, I have BOINC 4.13, PIR@H sextant 4.27
WinXP Prof SP1
P4-2,6 GHz, 512Mb RAM
RADEON 9600 Series VideoCard

1. Click "Show Graphics" on compass_*** WU
2. Minimize it
3. Close Graphics window
4. Click "Show Graphics" again - no windows were shown, but it presents in taskbar
5. Select "Restore" from context menu of Sextant window Title - windows was not restored
6. select "Move" from context menu and with cursor keys I moved window to desktop window center.
7. Stretch sextant window up to normal size (it was only title)
8. *bug* Globus was a vertical line (not a sphere)
9. close window and after "Show Graphics" all was ok (and globus also was ok)

This also happens with graphics of other projects not only with Sextant. I tested it with CPDN and S@H (P@H and LHC has no WUs at this moment as you know). I think this happens with all BOINC projects.

In my project I develop I save not only a program windows sizes but also windows state.
I.e. when a program window is maximized or minimized I save this state, when a window is normal I save this state and windows coordinates and size.
When I start my program I load saved window state and sizes. When state is minimized or maximized I set windows size to default values, and when window state is normal I load window sizes.

A project I develop is not a BOINC project. I use Borland Delphi. A class for window objects (TForm) in Delphi has property that is named "WindowState". It has 3 values: wsMaximized, wsMinimized and wsNormal.

I don't know if it is present in C++, sorry. But I think the property must be there.

But, I found in MFC class CWnd 2 functions:
IsIconic Determines whether CWnd is minimized (iconic).
IsZoomed Determines whether CWnd is maximized.

May be this can help you?

Just small specification.

When I select "Move" command I use cursor keys to 'capture' the window because it placed out of the screen in top left corner. The cursor is shown as arrows.
Then with the mouse I droped the window in desktop center.

8. The Bug is fixed (sextant 4.31) ;) The Globus now is volumetric, instead of flat. :)

I wrote an email to boinc_dev mailing list about this problem with possible solution (a few lines of code). Changes were made in api / windows_opengl.C.

Dr. David Anderson included these changes in cvs base.
