Boost not caching with replacePngTags.php enabled

Hi,

Boost runs beautifully on several of my sites. Today I tried to enable Boost on a site that utilizes views and it simply does not cache. I am experienced at installing boost and feel all my settings are correct. For all my sites I've left everything default except the custom .htaccess code of course. I tried uninstalling and reinstalling boost. No beans.

A cache directory is successfully generated, along with www.mysite.com and mysite.com, though they remain empty.

Is there a special configuration if views is enabled? I've tried searching for views and boost but cannot find any posts with a similar issue.

My setup:

Drupal 6.16
Boost 1.18
Views 2.10

MySQL database	5.1.30
PHP	5.2.13
Web server	Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8m DAV/2 mod_fcgid/2.3.5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635

.htaccess including boost generated code
