I am running a Wordpress site with Windows Server 2008 and IIS 7.5. I've enabled Wincache 1.3.5.0 with PHP 5.5. and I've confirmed that opcode cache is enabled with phpinfo(). See screenshot: https://www.dropbox.com/s/kyw4o6yg5ufa960/Screenshot%202013-12-19%2014.51.53.png
However, the compatibility check in W3TC does not recognize an opcode cache as installed. https://www.dropbox.com/s/jhlg9t6yp9n095j/Screenshot%202013-12-19%2014.53.30.png
I've enabled Page Cache, Database Cache, and Object Cache with "OpCode: Wincache", which does appear in the drop down as a viable option. However, when I look at the debug info at the bottom of the page it appears as not working 100% correctly.
If I refresh the page the debug timestamp is not changing, which leads me to believe some caching is happening. Plus in the DB and Object debug info, some queries are cached:

However, in the Page cache it ALWAYS says "Status: Not Cached" https://www.dropbox.com/s/y8th0iccpl7j4b6/Screenshot%202013-12-19%2015.00.59.png
If I switch Page caching to disk basic, then I get no debug output at all for page caching.
What is going on here? It seems like some of the caching features are working with W3TC and Wincache, but not Page caching. I'd really want to get Page caching working more than any of the other caching types. Am I doing something wrong with my configuration?
I'd appreciate any insight anyone could provide to
