I have not found the solution yet, but for those of you, who have

"If you design an application for Windows 98 and/or Windows 2000 with

application may fail. If your application tries to take over the
foreground under restricted conditions, your application flashes in
the user's taskbar. Your application can take over the foreground
under one of the following conditions ..."

Indeed, SetForegroundWindow causes the target window to flash on the
taskbar...
