Incorrect document display in Zoho Docs

Incorrect document display in Zoho Docs

I seem to be having a mix of problems when viewing a PDF uploaded into Zoho Docs. On the PC I am using, everything looks fine but viewed from other machines, I see two main problems :

1. In Internet Explorer on an XP machine, I get a blank screen and the document is not visible at all
2. On the same machine using Google Chrome, the document does appear but the left margin has gone and the first few     characters on the left side are missing.

Any ideas
