In Zoho Writer, it seems that anytime a document grows to more than 3000 words or so, the application becomes incredibly slow.  If I click in a different spot in the text, it takes forever for the cursor to get there.  If I happen to click outside the browser, it can take a very long time for the cursor to get back to my spot in the document. Scrolling also becomes incredibly sluggish. I have tried this in Firefox and Internet Explorer and I have tried it on three different computers running Windows XP and Vista. The problem remains the same everywhere.  Is there anything I can do speed this up, like some settings somewhere, or is it just the nature of this webapp?
