Copy and Pasted Text Behaves Erratically

Copy and Pasted Text Behaves Erratically

Firstly, I'm a long time user of Zoho apps.  I always extol the virtues of Zoho to my students and colleagues.

But I have a serious problem in the writer app.

Problem: 
When copying and pasting text from another source (ie:   Google Docs, simple online forms, even Zoho Notebook text ), the pasted text behaves erratically upon further formatting in the Writer app.

Behavior: 
When trying to block indent a text segment, entire text indents.
When trying to center a text segment, entire text centers.
When striking return key once, double spacing occurs.

This was not a problem before. 
I'm having students build resumes in a simple online form and then when we try to copy and paste these simple text drafts into Writer, its a formatting disaster.   Last year this was not a problem. 

FYI:  I've got about 100 students getting very frustrated.  In comparison to Google docs, google docs doesn't behave this way.

Mac OS 10.5.8
Firefox 3.6.9
Safari 4.1.2
