Use 'GetOpenFileName' in GTK for Win32

["Bruce" <bruce1914 uestc edu cn>]

Dear All,

	I am programming an IDE using GTK under Win32.
	I see some article says that using 'GetOpenFileName' function
instead of GTK's file selection dialog API, I can get a Win32 native-look
file selection dialog. However, I tried this, but get some problem. The
Win32 file selection dialog really opened, but when I close the dialog and
press anywhere on my GTK window, the file selection window pop-up again
unexpectedly.
	
	Is there anyone successfully used 'GetOpenFileName' function on GTK?

	Thanks!
