Thanks.

You're welcome. A little testing till now. Two issues now:<br>
1. if I run simspark and monitorspark and then connect an agent, the
agent won't appear in correct color (it's gray instead of blue). If I
close the monitorspark and run it again, it's OK.<br>
2. Sometimes when I connect the first agent, monitorspark crashes.<br>
<br>
This is what I get from gdb:<br>
Program received signal SIGSEGV, Segmentation fault.<br>

<pre wrap="">I just wander whether we can remove the follow codes in inputsystemsdl.cpp:
00082 if (!SDL_WasInit(SDL_INIT_VIDEO))
00083 {
00084 if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_NOPARACHUTE) < 0)
00085 {
00086 GetLog()->Error() << "ERROR: (InputSystemSDL) SDL
not initialized!\n";
00087 return false;
00088 }
00089 SDL_SetVideoMode(0,0,0,0);
00090 static SDL_SysWMinfo pInfo;
00091 SDL_VERSION(&pInfo.version);
00092 SDL_GetWMInfo(&pInfo);
It works in my system without these codes,
but I am not sure in other system.

The comment above the following code says that video should be
initialized for input system to work. BTW, by removing the last four
lines the window won't appear. So I think it's safe to retain SDL
initialization here.<br>
<br>
Thanks,<br>
