mfunc not work fine using WP Super Cache

I use WP Super Cache and now, I want to use AdRotator to show ads on my blog.

Ads are not static content, so I activate HALF ON mode (as FAQ of WP Super Cache says) and before, I write on my sidebar.php:

<!–mfunc adrotate_banner(‘1’) –>
<?php echo adrotate_banner(‘1’); ?>
<!–/mfunc–>

And doesn’t work. So even I tried:

<!–mfunc echo adrotate_banner(‘1’) –>
<?php echo adrotate_banner(‘1’); ?>
<!–/mfunc–>

With both, the first time I load the blog seems to be ok. But when the page is cached, and I reload, the sidebar (where I put the code) disappear.

It’s a big trouble to me. Any idea? Thanks a lot
