refresh of non-http pages with force_ssl_admin

I could use some help debugging a problem.

I am using WordPress HTTPS to secure certain pages (not the entire site), that works ok.

But when I want to secure the admin along with these pages( by using force_ssl_admin or by checking the box in the WpHTTPS plugin to force ssl admin), I get infinite refreshes on all of the pages that were to be delivered normally (all http pages).

The https pages and the admin are correctly served as https, and with no refresh loop.

—

What I have discovered, is that when the Force_ssl_admin is set, the pages that are http, load with an https:/admin-ajax.php call that seems to cause the site to oscillate between http and https, so there is a constant refresh of all of the http pages.

Is there any way I can get this working properly with setting etc?

My site was working fine for 6 months with version 3.3.0 (or lower), when I upgraded to any version after that, the constant refresh occurs. I have also discovered that one of my main plugins (Events Made Easy) could be interfering in some way. If it is disabled, the refresh stops, but I have contacted that author and he is not able to replicate the error.

Any help is appreciated – I would really love this to work.
