is there any way to position the inputbox$ window?

Yes. The code is really very complex. It crashes in this loop:

(bm file)

While GetMessageA(_Offset(msg), 0, 0, 0) > 0 ' gets a message from our application's message queue.
        dummyL = TranslateMessage(_Offset(msg)) '  performs some additional processing on keyboard events
        dummyO = DispatchMessageA(_Offset(msg)) '  sends the message out to the window that the message was sent to
Wend

Good news. In version QB64PE 32 bit 3.12.0 works as expected.
