Good suggestion. Although according to
msg.c:2524: Test failed: IsWindowVisible() should return TRUE
IsWindowVisible() detects an invisible desktop under win2k just fine.
According to test.winehq.org results Win95 and Win98 are not affected
by desktop visibility at all (thanks to their broken services model),
and IsWindowVisible() doesn't detect an invisible desktop under NT40.
