I can't reproduce this on my system.  I'm running 64-bit Windows 7, 
emacs-24.2-1, the latest Cygwin snapshot (2012-08-27), and the test 
version of the X server (1.13.0-1).  Here's what I tried:

1. Start mintty from the "Cygwin Terminal" shortcut.

2. $ startxwin

3. [still in the mintty window] $ DISPLAY=:0 emacs -Q&

4. In the resulting emacs window, C-z.

5. Left click on the emacs icon to de-iconify emacs.

The cursor blinks and emacs responds to keyboard input.

Are you able to reproduce your problem with 'emacs -Q'?

P.S. Shouldn't this discussion be taking place on the cygwin-xfree list?
