Another annoying thread

[Necrofear]

Sorry, I realize I posted very similar code a few days ago, but I have another question about it.

// Windows.cpp

#include <windows.h>
#include "Controls.h"

const char g_szClassName[] = "WindowClass";
HWND hWindowHandle;

char STSUsername[256];  // STS = String to store
char STSPassword[256];

And a header that works and shouldn't have anything to do with my problem. Oh, by the way, here it is: Whenever I click on either the username or password edit boxes, the dialog closes. Is this meant to happen? Is there some code that needs to be added to prevent this from happening? I've looked through a few examples, and in them, it only mentioned the edit boxes in the .rc file, so I did the same. I'm on XP Pro, and using Dev-C++ if it matters.

Thanks in advance for any future replies.
