 Hi,

 I've used every previous version of Wordpress on my WAMP install and have
 never had a problem... so, it must a problem with Wordpress.

 I've honed it more on the exact problem.

 Note: This is after updating to the version you linked in your response,
 the same issue is happening.

 Saving a CSS file works properly, but ANY php file crashes
 WAMP/Apache/MySQL. Whatever is different between saving a CSS file and
 saving a PHP file, is what's causing the issue. I also tried multiple PHP
 files, footer.php, header.php, all crash in the same way. All CSS files
 however, saved properly.

 It seems to be this file that's timing out / crashing...

 admin-ajax.php

 Here are more details from the Chrome network section:
