Closing the window with _IECreateEmbedded() content

[PlkMarudny]

I use a simple script (below) to display a webpage that takes a selected text as a parameter, when the "^q" keystroke is pressed. Unfortunately, when an user open 3 windows using he script below, Autoit hangs. That's ok, I tried to keep only one window open, closing the previously opened window. But it turned out that always the newly opened window is closed, despite using the handle to the previous window, as confirmed by the console output ... Is there any error in the script?
