Any Zoho response to images not working properly in Firefox?

Images in Zoho writer continue not to work correctly in any version of Firefox 3+ thru Firefox 6.0.  They often do not align correctly around text (left or right) and if they do, they can NOT be moved by dragging.  I've tried this on several computers with various versions of Firefox. I have posted this problem before but no response from Zoho. Please help with this.
