Seems like I'm monopolyzing this thread but I thought that after two
days
of trying to figure out the matter, there may be at least one poor
soul interested in what I have come up with.

Since I still have no success in calling window.lift(), I've gone with
:

hwnd = string.atoi( window.frame(), 0 )
win32gui.SetForegroundWindow( hwnd )

On Win98 (and reportedly on W2k), however, the nasty foreground window
restriction messes up things. To circumvent that, I ran the following
C code:

#ifndef SPI_SETFOREGROUNDLOCKTIMEOUT 
// older version of winuser.h doesnt have it defined
#define SPI_SETFOREGROUNDLOCKTIMEOUT 0x2001
#endif

SystemParametersInfo(SPI_SETFOREGROUNDLOCKTIMEOUT, 0, (LPVOID)0,      
               SPIF_SENDWININICHANGE | SPIF_UPDATEINIFILE);

which apparently switches off some sort of
foreground-setting-lock-timeout-thing

Hope it helps someone out there.
BTW, I would still be interested in solution/explanation of the
.lift() problem.
