Tor Lillqvist fafe735f13 Don't call CloseHandle() on the HMODULE returned from GetModuleHandle().
2003-09-02  Tor Lillqvist  <tml@iki.fi>

	* gdk/win32/gdkdisplay-win32.c (gdk_display_open): Don't call
	CloseHandle() on the HMODULE returned from GetModuleHandle().
	Didn't cause any harm, but didn't do anything useful either. When
	running a GTK+ program under MS's debugger, the CloseHandle() call
	would cause a "first-chance exception" in ntdll.dll to show up.
	(The exception is caught appropriately if you let it proceed, but
	it confuses the person using the debugger). Thanks to Bruce
	Hochstetler for noticing.
