Issues with starting live games from within the chat

1. An error message appears, saying the file (replay) could not be found. Unfortunatly this error message is hidden, the only thing I see is a big black empty screen. And it won't go away until I alt tab to my desktop. I have to kill the supcom process to be able to try to watch the replay again.
2. Sometimes it gets worse than above, because not only does the screen get black and nothing happens, but alt tabbing also doesn't work and CTRL + ALT + DEL somehow interrupts the video signal. I can't see anything anymore. My monitor just turns off. I have to turn off the pc and boot it again.
3. live replays are unavailable even if the game is more than 15 minutes old.
