[New comer]

I opened a word file I already worked before and updated and saved it - it is
normal so far. After keeping working for a while, when I tried to save it, I
got a message saying I cannot save it. The existing file name, while it is
still open and i am working now, is suddenly changed to "xxxx.tmp". I had to
save as with other name.

I used MS Word 2007 Enterprise and worked under 2007 Office Groove.

Any comments are welcome.

Thanks,
