Conflict with Context module

Hi to all,

I'm using 2.x.dev (Feb 2011) for a multi language website.

I'm using Slideshow to show up a group of banners according with current language and all works fine (views is cached "once fo all").

I'm now intrducing Context module for a better management of blocks and a problem happens.

I create a "Sitewide" Context associated with the block indicated above, but:

1) It work correclty under admin role: block is showed with correct banners and slide effect,
2) Works good for Anonymous role only at first page sight; if I REFRESH the page the slide controls disappear and only one banner is showed.

Any ideas about this problem?

Thanks!
Bye
