Windows sends a message with the id WM_DISPLAYCHANGE whenever the user applies
changes to screen resolution/depth. (In fact, with typical MS "panache", they
send the message twice - same params each time - and don't talk to me about
WM_ACTIVATE!). I have no experience with either Tkinter or Idle, but you could
check the Win sources and see if this message is at least handled by the Windows
message handling code. That might indicate a possible solution. I don't actually
know where this message is derived from, but I'd be surprised if it was the
graphics card driver.

Sounds like a different problem - perhaps that is the HW/driver. Perhaps you
