Hi.
CefGlue itself did not write anything in console, and i'm did not know how to suppress this messages.
I'm already take some discussion in past, about this, but i'm not sure that anyone it is implemented (adds API to provide own log listener / remove existing listeners).
There is not bad idea to ask this question at ceforum.
If you ask, please sent link to topic here. Thanks.
I'm think, that it will be very useful feature, 'cause can help diagnose some specific problems.
PS: About sandbox - i'm not sure that it is really can be useful under .net, 'cause it should be initialized very early, what in fact did not happens with .net process (i.e. just after WinMain/main), so even if sanbox will work - it will be more weaky than it done in native. But if it is absolutely required, it is not too hard to create own CLR host in native, and then run own app with sandbox, but i'm also not sure that it is really work. But standard way is just doesn't use sandbox.
