A second windows appears named: "Tera Term: Log"

Kommentar
I have nearly the same issue here. I'm using TeraTerm 4.8.5 under Windows 7 (64 bit). Whenever I block the TeraTerm window by moving with the mouse, the hardware flow control becomes active and the log file loses a few characters. I have verified that the computer sending the data really stops the transmission if RTS goes high, still the TeraTerm log loses characters. If I don't block the TeraTerm main window (so the RTS/CTS lines do not get active) , the log file is completely OK also with binary files.
