postscript upodate doesn't work :(

[Giorgio Corani]

hi!
I've just updated lyx to the 1.1.6fix1 release.
Although it works fine, I'm experiencing some problems with postscript 
preview.
As a matter of fact, when  I try to update it, gv continues to display 
the same postscript file; moreover, if I close gv and follow the menu 
(view->postscript), I get once more the old file.
In order to get the updated version, I have to close lyx, delete the 
.lyx directory in /tmp and re-open the file.
Ideas?
should the 1.1.6fix2 fix that?
