Did you consider implementing the approach Robert Shearman has pointed out?

Better test for visible desktop, should be working on all platforms.

Here is another way for testing for a visible desktop which just came
to my mind (based on the EMF test failure analysis and the description
from http://www.codeproject.com/gdi/cliprgnguide.asp):

static int running_on_visible_desktop ()
{
    BOOL visible;
    HWND desktop;
    HDC hdc;
    HRGN hrgn;
    RECT rc;

desktop = GetDesktopWindow();
    hdc = GetDC(desktop);
    hrgn = CreateRectRgn(0, 0, 0, 0);
    GetRandomRgn(hdc, hrgn, SYSRGN);

visible = GetRgnBox(hrgn, &rc) != NULLREGION;

DeleteObject(hrgn);
    ReleaseDC(desktop, hdc);

return visible;
}

Better test for visible desktop, should be working on all platforms.

Go for it, could you send a patch to wine-cvs?

Better test for visible desktop, should be working on all platforms.

Simple qu, since I'm not that familiar with Wine yet.

How can I run a desktop under wine? Is it poss to have two or more apps  
running concurrently in the same wine session?

TIA.
