I've always just been trialing in LCB (check out the attachments)
Surprisingly also "search youtube", "download subtitles" even "Exit XBMC" aren't working for me while the others are working.
From your screen capture, there's no indication that the youtube and download subtitles commands didn't work. The only command indicating a problem is the orange line.
[Edit: I see the youtube line looks like it may be grey -- I didn't notice that before, but that's not an error per se.]
In general, if you roll over messages in the history panel, you'll get a popup message providing more details if there are problems. You can also enable logging and look at that file, as well as post the full log to provide more information.

The "Exit XBMC" command is not captured in your image. I'm not sure why that wouldn't work for you.
Can I ask, (a) what version of VC are you using, and (b) did you follow the video tutorial or wiki documentation for installing the XBMC (Frodo) configuration of VC? In particular, the part about installing the VoxTools addon within XBMC?

I have now enabled the Pandora addon in my XBMC Frodo installation and created a VC command per our suggestions above; it seems to be working. I can't really test it because I live in Canada.
