MessageBox changes a str255 variable

[Grant Hudgens]

I am working on an iTunes plugin using their own SDK the only thing I have changed is adding two MessageBoxes. iTunes sends stream information to a function in the plugin where I am able to access it. Here is the code. case kVisualPluginPlayMessage: if (messageInfo->u.playMessage.trackInfo != nil) visualPluginData->trackInfo = *messageInfo->u.playMessage.trackInfoUnicode; else MyMemClear(&visualPluginData->trackInfo,sizeof(visualPluginData->trackInfo)); if (messageInfo->u.playMessage.streamInfo != nil) visualPluginData->streamInfo = *messageInfo->u.playMessage.streamInfoUnicode; else MyMemClear(&visualPluginData->streamInfo,sizeof(visualPluginData->streamInfo)); //MessageBox(NULL, visualPluginData->streamInfo.streamTitle, "Stream Title 1", NULL); MessageBox(NULL, visualPluginData->streamInfo.streamTitle, "Stream Title 2", NULL); visualPluginData->playing = true; break; streamTitle is an str255 variable passed on by iTunes. Now, if I run it like it is it will display nothing for streamTitle. If I run it without the first MessageBox uncommented it will display nothing for streamTitle the first time, but the second MessageBox will have information in it. This is driving me insane haha and any help would be greatly appreciated.
