Hey malte, just updated to 1.0.5. popen didn't work for me either.
On the bright side, I was able to get a workaround for web/remote servers with a lot of help from other members.
This is my thread from the linux section
Linux fix for web/server failure.
Turns out the child process was inheriting the web/remote server from xbmc. Which explains why it seemed when I manually killed xbmc after running applaunch.sh and the web/remote servers failed, that it was an opening of xbmc issue. When really no matter what way it's opened in applaunch.sh it's still going to have the web/remote server issue.
The easiest fix came from members enorlin and artrafael with the command "at". Which I think could be implemented into RCB very easily with only one small extra script necessary. How this would work on windows I don't know though. But on xbmcbuntu it works like a charm.
At least the mystery can be put to rest on why it was happening.
I'm loving the new test version btw!
Thanks Malte,
-David
EDIT:
Popen works, got ahead of myself and didn't chmod applaunch.sh oops!
Web/remote servers still fail on startup though.
And there seems to be a bug where Backspace will launch the game
EDIT:
As far as the bug, once you hit enter on a game, no matter if you hit backspace or escape your trapped in the launch game and select disk screens with no way to go back, only to launch the game.
