Open IT Online v1.1.1 solves the problem occurring with Zoho Viewer, in particular we have:

• adapted the url used for Zoho Viewer service: at the end of February, Zoho updated their online service and now it requires, as input, an expiration date. Documents converted by Zoho Viewer through Open IT Online will expire after 1 day;
• added support for Firefox 3.0b5pre.
