Guys, I had this issue even with r103.2 for a big project (smaller ones seem to be ok). I finally got fed up enough to try and work out a solution. Basically what I did was download wampserver, install it (very easy), then exported my project unminified to the "www" directory under where wamp was installed.
Then I was able to browse straight to "localhost/c2game" and woohoo! works everytime <img src="smileys/smiley36.gif" border="0" align="middle" />
