Let me start with this intro: 2.22.4-1 included a fix for GIO plugin 
loading on Win32[1], but once again they lumped Cygwin together with 
MinGW.  Of course, not only did this not need to be "fixed" on Cygwin 
but they outright broke GIO and everything that depends on it, and I got 
to pick up the pieces.  Hence the need for 2.22.4-2, which behaves as it 
should.

So you might as well forget about 2.22.4-1, and focus on whatever issues 
you appear to be having with GIO.

This is the expected behaviour.  GtkFileChooser uses GFileMonitor (whose 
backend uses FAM/Gamin) so that changes to the directory being browsed 
are displayed.

I haven't seen this behaviour with other GTK+ apps, so I suspect it may 
be (YA) emacs/gtk+ bug.  (Googling shows that this seems to happen a 
lot.)  You may want to try these patches and see if they help:
